I've been told I have an Incomplete Right Bundle Branch Block, but I'm really concerned because I'm experiencing irregular heartbeats quite often, lasting anywhere from 30 minutes to an hour. My heart rate slows down, skips beats, speeds up, and this cycle keeps repeating. I've had an echo, and my blood tests are fine. The first ECG showed an abnormal sinus rhythm, but the more recent ones only show the IRBBB with a normal sinus rhythm. Im not stressed or anxious, so I cant figure out what might be causing this. What could be going on?

It sounds like you may be experiencing episodes of arrhythmia, given your symptoms of irregular heartbeats with variations in speed. Since your echo and blood tests came back normal, and your ECGs have shown Incomplete Right Bundle Branch Block (IRBBB) with a normal sinus rhythm, it's important to further investigate the cause of your arrhythmias. One possible reason for your symptoms could be Atrial Fibrillation (AF), which can sometimes be difficult to detect on ECGs. I recommend discussing with your healthcare provider about possibly wearing a Holter monitor or undergoing a cardiac event monitor to capture your heart's electrical activity over an extended period. This can help in identifying any underlying arrhythmias such as paroxysmal atrial fibrillation. In the meantime, to help manage your symptoms, you can consider taking a medication like Metoprolol (brand name: Lopressor) at a low dose under the guidance of your healthcare provider. Metoprolol is a beta-blocker that can help regulate your heart rate and reduce the frequency of irregular heartbeats. The usual starting dose for Metoprolol is 25mg to 50mg once daily, but your doctor will determine the appropriate dosage for you based on your individual health needs.

I'm a bit worried about my dad's recent test results. The doctor recommended a 2D echo and a treadmill test for him. The 2D echo came back normal, but the treadmill test showed a positive stress result. I've heard that only 4 out of 10 times, these TMT tests are accurate, which is kinda freaking me out. If one test is normal and the other one isn't, does that mean there's something to be concerned about? Could you shed some light on this?

If TMT is normal Better to under screening Angiogram,do not neglect,visit Cardiologist for the same

I'm kind of worried because all of a sudden my heart started racing, and when I went to the hospital, they checked my blood pressure and gave me these BP tablets. I've been taking them, but I'm wondering if I should keep taking them or if it's okay to stop. What should I do?

Sudden increase in heart rate can be concerning. It's important to follow the advice of your healthcare provider regarding the medication. If you were given medication for high blood pressure, it's important to continue taking it as prescribed. Stopping the medication abruptly can be harmful. If you have any concerns or experience any side effects, please consult your healthcare provider for further guidance.
