Avatar n tn Thank you for your quick reply. It makes a little more sense now. No one has explained it to me and no changes had been made so I got a little nervous.
Avatar f tn I am taking Digoxin for tachycardia--my cardiologist says that while there aren't good studies available for cardiac meds while pregnant Digoxin is believed to be safe. It is not a betablocker, however the dr felt the digoxin would be safer than a betablocker while preggo. Also the changes in your blood volume while pregnant may correct the tachycardia.
4237975 tn?1351595953 Lifestyle changes include limiting physical activity, eating a heart healthy diet, completely avoiding alcohol and/or tobacco use, practice relaxation techniques like yoga and keeping a daily weight diary to keep a tab on weight changes. Medications such as digoxin and beta blockers help to improve the pumping capacity of the heart. Discuss these options with your consulting doctor. Hope this helped and do keep us posted.
Avatar m tn Dear Doctor I am writing this from India My Son was diagnosied (provisional diagnosis) of Viral Myocarditis when he was 2 weeks old and he was in ICU for 2 weeks (in Dec 2005) . When his condition became stabe he was discharged and was on medication - Carnitine, Lasix & Digoxin. When he was 1 year old, echo revealed improved EF of 45-50% and Doctor stopped Lasix.
1591333 tn?1297733419 The left venticle will dilate to increase blood flow with each stroke and the heart rate will increase the cardiac output (amount of blood pumped per minute). If the system is dysfunctional, medication, etc. can change the dynamics. For instance heart failure increases blood volume and the kidneys react as if the individual is losing blood...the increase of volume further distresses the heart and kidneys continue to believe the system is losing blood.
Avatar f tn The doctors are a bit torn. Her general practioner was quite sure it was heart related as she said she's never seen acrocyanosis like this before (so bad that her entire arms and legs will turn blue, her chest will get mottled, but her mouth stays okay). What I'm wondering, and maybe this is a long shot: does heart failure have any effect on body temperature? Our daughter has had several low readings (via rectal thermometor). Not seriously low, but in the mid 97s (97.1 - 97.7).
Avatar n tn The difference of normal cardiac output has a variation of about 34%. Therefore. just based on cardiac output variation the PAP can vary by 34%. I have read your doctor's report (what you provide) to you, and there is not any opinion that is not in keeping with a good analysis and evaluation. I think you may be reading information that is confusing, however, if you don't trust your doctor's evaluation then see another doctor.
Avatar n tn A low ejection fraction is one of the predictors for sudden cardiac death and potentially your father would be a candidate for an implantable defibrillator. The medical treatment should include digoxin, beta blockers (carvedilol) and an ace inhibitor. Whether your dad should have surgery depends on the severity of the mitral valve leakage and his overall general condition. At times the heart function and mitral regurgitation can improve on a good medical program.
1459433 tn?1285693332 Is there anything they can do to cut those risks? Does low cardiac output cause headaches? We already know she has low cardiac output which causes dilated capillaries in her face(the headaches started about the same time as the bright red face). Any info would be helpful as we are not scheduled to see the card or neuro for a couple of months.
Avatar n tn QUOTE:"by PikaPika88, 3 hours ago A doctor works at the country side told me..... MI won't affect the blood pressure. Many MI patient remain in normal range of blood pressure. She didn't mention about the heart rate (pulse)." How can it not effect vital signs? There has to be a misunderstanding! The system compensates when there is low cardiac output. MI damages heart cells and impedes left ventricle contractions. Impeded left ventricle reduces cardiac output. ....
Avatar f tn High ventricular rate leads to insufficient diastolic filling time. Digoxin slows down the conduction in the AV node and increases its refractory period, and it can reduce the ventricular rate. The arrhythmia itself is not affected, but the pumping function of the heart improves by improved filling. The use of digoxin in heart problems during sinus rhythm was once standard.
Avatar n tn I recently was diagnosed with the above along with arryhmia and aortic and mitral valve insufficienc. I have low pressure normally so my doctor prescribed 2.5mg of lisinopril. After taking it for 5 nights I've started to experience dizziness when I get up during the night. I also wake up with a dry cough. Tuesday my blood pressure was 86/53. Is there any other treatment for this "mild" case of cardiomyopthy other than blood pressure lowering medicine?
Avatar f tn I experienced AFib lately and when to hospital. Doctor put me on Digoxin, just wondering if anyone is on this drug and if it is working. This discussion is related to <a href='http://www.medhelp.org/posts/show/262663'>Synthroid and frequent heart flutters</a>.
Avatar f tn I will suggest decreasing the dose of the beta blockers and may be add digoxin to improve the cardiac output. Angiography may help if there’s a suspicion of the coronary artery disease. Another point is that if there isn’t marked collection of fluid in the body due to the heart failure, then lasix can also cause worsening of the symptoms. Maybe he needs another evaluation to decide about his drug dosage. I hope that helps. Please do keep me posted. Kind Regards.
Avatar n tn I was a patient with heart failure and hospitalized for several days. The discharge from the hospital provided written instruction saying weigh yourself every morning and if there is a few pounds gained over night to contact the doctor as that could indicate being in heart failure mode and fluids were backing up into the lungs and/or peripheral locations... the heart would not be strong enough to output the amount of blood received from the lungs. .
Avatar m tn t ever heard of an increase of the EF when pulse rate increases. Cardiac output (CO) is increased and that metric is the total amount of blood pumped into circulation based on heart rate for one minute. A pacemaker would control the heart rate. QUOTE: "My GP told me to cut the Atenolol in half and gave me an RX for Enalapril Maleate 5mg daily. He said hopefully the Enalapril would dilate the output artery(my words?) and increase EF and blood flow thus reducing fatigue".
Avatar m tn The cause would/could be a low cardiac output secondary to pumping and/or filling dysfunction. Severe valve regurgitation would lower cardiac output as some blood flows back into the upper chamber and not pumped into circulation.
Avatar f tn If MVP is serious such as to reduce the cardiac output, the cardiac output is reduced, the heart will over compensate with an enlarged heart. An enlarged heart can effect the electrical pathways and that with RBBB can cause ventrical tachycardia. "People who have a heart attack and develop a bundle branch block have a higher chance of complications and death than do people who have heart attacks and don't develop a bundle branch block.
Avatar m tn The contribution of the heart to the regulation of blood pressure is through changes in cardiac output. Cardiac output is defined as the product of heart rate and stroke volume. Either can be modified by climatic forces. The heart rate component is regulated by the autonomic nervous system, so its level of activity depends on the intensity of the stimulus at the time.
Avatar m tn I recently had a right heart cath due to continuing symptoms of shortness of breath, chest pain on exertion, cold/tingly hands, swelling in ankles, fatigue (especially on stairs), "foggy" thinking episodes, pounding heartbeat at times. The results were a bit confusing to me and the doc didn't discuss much of it over the phone. All I have are a limited set of the test results as follows: PA Pressure - 88.9; Cardiac Output - 16.2; SBP - 150.
Avatar n tn The problem with it is that it has a concerning side-effect profile. It is much worse than digoxin from that stand-point. Patients frequently develop thyroid and liver problems, they also have to have their eyes and lungs checked routinely to rule out further complications. We typically only use it as a last resort drug, or for a short period of time. Since the side-effects are usually related to the length of exposure, we tend not to use this medication in young patients.
Avatar n tn Extreme fatigue is a condition that exists. I have been told by my cardiologist and cardiac surgeon that these conditions should not exist related to my valve regurgitations. I also have been diagnosed with Fibromyalgia and a peripheal (sp?) sensory neuropathy. Should I be seeking a second opinion? Thank you.
Avatar n tn My experience for heart failure was normal blood pressure and a heart rate sustained at 115 bpm. The higher heart rate is to increase the cardiac output (amount of blood pumped/per minute). The increase is due to a failure of the heart to meet the system's demand for oxygenated blood with normal heart rate, and the increase of the heart rate is compensation for a low volume per heartbeat.
Avatar m tn Also the cardiac output may be inadequate, hence the breathlessness. For relief from your symptoms the blood flow and the cardiac output need to be improved. I would suggest to limit your walking, keep high risk factors like hypertension and diabetes under control and discuss the treatment options with your doctor. Hope this helped and do keep us posted.
Avatar m tn Eventually reduced cardiac output causes the left side of the heart to enlarge to compensate for the reduced cardiac output, and the left ventricle will begin to lose its contractility and as a consequence the systole EF will decrease.(Frank/Starling phenomonon). By and large, diastolic dysfunction is chronic process. When this chronic condition is well tolerated by an individual, no specific treatment may be indicated.
