digoxin and preload

Diastolic transmitral e/a ratio indicates left ventricular wall tension and intracavity pressure that impairs systole (filling phase called preload). Conditon decreases cardiac output with each stroke.

For instance there can be stenosis (narrow opening) of mitral valve and that condition it seems will not change the ratio time but the volume (preload) of blood into the left ventricle can change...both A and E would be equally affected by the stenosis of the valve or left ventricle size and rigid wall abnormality.

severe edema in feet/ankles/calves (sudden onset three weeks ago), constant (and loud!), breathlessness from even mild exertion, ear ringing, blurry vision, dizziness, wheezing (high-pitched, whistling sounds) and headache. I've also been told I am pre-diabetic The edema becomes so bad it's hard to walk. Should I worry about the possibility of CHF?

Hello, After 10 years of trying to get an answer, I finally got a diagnosis of cardiac preload failure, low VOxmax, and decreased AT. I have shortness of breath, palpitations/heart racing, chest pains, fatigue, lightheaded. Many many echos--three with bubbles. A PFO showed up on one. Normal cardiac cath--they couldn't see the PFO during the cath. Normal EKGs. Halters normal except for mild sinus tachycardia. Many pulmonary tests--all normal. I have MVP with trace regurgitation.

My husband and I would like to start trying for a baby but i'm on Betablockers for a tachycardia that no-one can find a reason for! i'm only on 1.25mg of bisoprolol, and would like to know what risks there are. I'm currently on a waiting list to see cardiology and find out what their opinion is but would like a bit of advice.

My father recenlty fell, fractured his hip and I have been getting contradicting information about digoxin, since he has low blood pressure and digoxin may not be safe for him.. Thank you This discussion is related to <a href='/posts/show/239460'>Dijoxin Level</a>.

I took Digoxin for a number of years in reponse to an atrial fibrillation event. My new physician did not feel I needed to be on it any longer. What are the side effects of discontinuing this medication? I have been off it for several months and some odd changes in my body.

There’s a third class of drugs which help by improving the contractility of the heart and that is digoxin. You should consult another cardiologist and maybe another echo will help in settling the matters. I sincerely hope that helps. Take care.

My cardiologist did want to do anothe ECHO to measure Aortic root and ejection fraction = (4.4cm and 55-60%). Because of increased Aortic root dilation, a CTA is scheduled for Sept 17. Question: If my CTA confirms ECHO Aortic root dialation, may this related to PVCs and PACs in any way? Does the Aorta dilation irritate the heart causing arrhythmia? Does the PVCs cause a stress on the Aorta from the extra pressure pulse after pre-load (assoc. compensatory pause)?

So I had a pretty crappy cold about a week and a half ago, now being on digoxin I can't take cold meds so I stick it out. Well the cold is now over and my teeth are hurting. I see no signs of abscess' and my mom thinks it might be a sinus infection. No from what I've read online they usually give amoxcillin to treat it. My question is has anyone else on digoxin taken amoxcillin? Is it safe. Being on dig I know there's a lot of stuff we can and can not take.

) you prob had low preload and therefore bp. So your heart compensated. The only way to keep co up is via increased sv or hr. So basically co( cardiac out put)= stroke volume ( amount of blood for each pump) x heart rate. I think in your case totally benign.

The Heart Rhythm Society did a few randomized trials to assess the efficacy of calcium channel blockers, beta-blockers and digoxin in SVT. A comparison of verapamil, propranolol and digoxin showed equivalent efficacy in a small group of patients. However, in general calcium channel blockers and beta-blockers are preferred to digoxin. Digoxin has been around for a long time! I used Digoxin over 50 years ago for my PSVT, and my recollection was that it did little to prevent episodes.

I have some Afib and some PAC's, my doc said Digoxin and Toprol do the same thing, I chose the Digoxin. Does anyone take the Digoxin for these conditions and it works? Which do you think is better?

s contractions are weaker than normal, and digoxin helps provide a stronger beating heart. If one has increased functionality of the heart, the drug may be dropped, also, there can be a tolerance that develops with digoxin that may require discontinuation for a period of time.

s my completely unprofessional opinion on what I know about digoxin, and I took it for a number of years as a kid for SVT. It's an old drug that's been used literally for centuries. I took it back in 1957. It's inherently toxic and if that fact was not enough to curtail its use, there's evidence that suggests the drug, even at dosages normally considered safe, can cause visual problems, serious skin rashes, and may significantly aggravate asthma.

I know if i was on digoxin i would look at the packaging the pharmacy gave me and go directly to the horses mouth so to speak and go onto the manufactuerers site and see what they have to say about long term effects, etc. They should tell you what the clinical studies showed, side effects and all of the pertinent information....good luck to you....

Then I found on the internet how toxic Digoxin could be with the other medicines I was taking, and that no one should be kept on it for very long. Since the second cardiologist removed Digoxin from my prescriptions, and I was healing and getting better, I think I must have been under a toxic level of Digoxin causing blood in my urine and poisoning affects of awake,eyesight,cuts,etc..

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.

I am wondering if you are uneasy about taking digoxin. If so, I would ask you cardio if you can get by with just the TOPROL XL. Digoxin, xanax, toprol xl, and lisinoprol seems like a lot of stuff to be taking. I am a runner and only take TOPROL XL 12.5mg. This knocks out my extra beats and really slows my heart down. A little seems to go a long way for me.

I am taking 25 mg of metaprolol split in half. Half in the morning and half at night. I also take 0.25 of digoxin and 5 mg of lisinopril. I have only taken the metaprolol and digoxin for less than a week so I guess it will stabilize soon. So far it has not really helped the arrythmias. If it does not help in several weeks maybe my cardio will change them. Thanks again for your help.

I am limited so much to what I can and cant do. I think its mainly due to the digoxin. So I was wondering if anyone out there has been on the digoxin and switched to something different. While on the digoxin did you have severe heat intolerance? I haven't been able to tan in 3 years or go to the beach. Pretty much all summer activities during the day I can not do. I get so dizzy and disoriented in the heat that it actually causes me to have attacks.

Cardiomyopathy has been ruled out. Everything has been ruled out. It is definitely preload failure. Preload failure is rare and almost always responds to fluid increase and/or an exercise regimen. I tried all of that a few times. It's amazing to see what doctors will do to get you out of their office when they don't know what to do with you.
