Pounding or Forceful Heartbeat

sojka123

For about 2 years I've noticed a more forceful than normal heartbeat.  It is NOT fast, or irregular - just stronger than normal. (Docs call this positive inotropy)  I have a good cardiologist but he is now scratching his head.  I've had an ECG, ultrasound, holter monitor, 2 weeks "King of Hearts" monitor, sleep apnea work up and sleep study, thyroid and parathyroid work up, also tests for adrenal tumor. (blood and urine catacholamines).  I have even had the new cardiac CT scan and have a Ca score of zero! ALL NORMAL.

The symptom is more noticeable lying down (many rhythm issues are), does not change with exercise.  Never any chest pain, or any other symptoms of cardiac problems.  I do take Atenolol (50 mg in the AM) and that helps.  (if I skip the dose the beat is much more noticeable and strong).  I have moderately elevated BP but controlled with medications.

ideas for next steps?  tests I should pursue?

Your heart tests sound wonderful, the results that is. If a person can feel their heart beat it's called "palpitations." It's not that unusual and not a disease in itself. I'm glad you had it checked out.
