I am now 53, (F), have have testing from my pulmonologist and cardiologist, including various
stress tests, EKG, Ultrasound. My heart will race after light activity, or after eating, and this is happening on an increasingly regular rate. The pulmonologist made a comment that I would go from aerobic to anaerobic at an early stage with exertion. My cardiologist is recommending a right cardiac cath as the next step of testing? Are there any other options?
