  1. ECG Utility
    An ECG (electrocardiogram) is effective for detecting heart issues in a 50-year-old male. It can identify arrhythmias, past heart attacks, and ischemia.

  2. Limitations
    Not all heart problems are detectable with an ECG. Additional tests like an echocardiogram or stress test may be necessary.

  3. Symptoms to Watch
    If experiencing chest pain, shortness of breath, or palpitations, an ECG is often recommended. Discuss symptoms with a healthcare provider for tailored advice.

I'm feeling really bloated and my stomach is causing me some breathing troubles. On top of that, I'm suddenly experiencing a lot of anxiety. Could this be linked to a heart problem? I'm really concerned and would love some insight.

I've been dealing with sinus tachycardia, and my doctor suggested I try met xl 12.5 mg. I've been on it for a few days, and while my resting pulse rate has dropped a bit from 100 to 90 bpm, it still jumps to around 105-110 bpm when I'm doing normal activities. I'm wondering if it's safe to up my dose from 12.5 mg to 25 mg, and how long would be okay to stay on that higher dose?

It is not recommended to adjust the dosage of Met XL without consulting your doctor. Increasing the dose from 12.5mg to 25mg should only be done under the supervision of a healthcare professional. They will assess your condition and determine if a dosage adjustment is necessary. Please consult your doctor for proper evaluation and guidance on the dosage adjustment and duration of treatment

I'm 26 and I've been having anxiety symptoms. A couple of months ago, I experienced episodes of sinus tachycardia, and the ECG showed sinus tachycardia with ST and T wave depression in leads II, III, and AVF. I've had more ECGs since then with similar results, but my 2D echo was normal. My doctor suggested a TMT, which returned borderline positive with a low likelihood of significant CAD. During the TMT, METS was 8.8, BP was 15080, and the max heart rate was 187. I didn't feel any chest pain during the exercise. Do you think an angiogram is necessary, and what could be causing those ST and T wave changes?

Angiogram is needed any heart blocks..
