Can ECG detect heart blockage?

Doctor 1

Answered by 1 Apollo Doctors

An ECG Can Recognize the Signs of Blocked Arteries. But for further accurecy a CT coronary angiogram can reveal plaque buildup and identify blockages in the arteries, which can lead to a heart attack.

  1. ECG Utility
    An ECG can record the heart's electrical activity and detect some heart issues, but it doesn't directly show artery blockages.

  2. Detection Limitations

    • It may indicate heart muscle damage or reduced blood flow.
    • It cannot precisely locate or confirm coronary artery blockages.
  3. Further Testing
    For detecting blockages, consider tests like: a. Stress test
    b. Coronary angiography
    c. CT coronary angiogram

  4. Recommendation
    If there are symptoms like chest pain, consult a cardiologist for appropriate tests and treatment. An ECG is a starting point but not definitive for blockages.

I've been feeling really off lately, like yesterday before lunch I was sweating a lot and my whole body felt weak, especially my legs. I tried eating some chocolate and rice but I was still sweating. So I went to the hospital and they said my BP was fine, and my GRBS was 153, about 45 minutes after eating. The ECG said sinus tachycardia, borderline ECG, and short PR interval, but the doctors said everything's normal when they compared it to an old ECG I had. I'm worried because I take Esomac for gastric issues and Cardace for BP, but I've been having mild chest pains almost every day. Ive done tmt echo tests many times and they always come back normal, but Im so anxious about my heart all the time. Now, I get really tired just walking for like 20 minutes. What could be going on?

The ECG from yesterday shows sinus tachycardia, borderline ECG, and a short PR interval. Given your symptoms of sweating, weakness, and fatigue, along with your history of mild chest pain and anxiety about your heart, it is important to continue monitoring your heart health closely. Since your previous ECGs have been normal, it is reassuring that there are no significant changes at this time. Considering your current medications, Esomac 40mg for gastric issues and Cardace H5 for blood pressure, it is essential to continue taking them as prescribed. To address your concerns about tiredness and anxiety, I recommend discussing with your healthcare provider about the possibility of adjusting your medications or exploring other treatment options. In addition, it is crucial to maintain a healthy lifestyle, including regular exercise within your limits, a balanced diet, and stress management techniques. If you experience any worsening symptoms or new concerns, do not hesitate to seek medical attention promptly.

I'm experiencing some sudden pain on the left side of my chest and leg, specifically around the knee, and I'm not sure what's going on. The pain tends to come and go, and it's been like this since yesterday. There's no pain in my hand, just the leg and chest. Do you have any advice or know of any tablets I could take to help with this?

"Based on your symptoms of sudden chest pain and left leg pain, it is important to rule out any serious conditions such as a heart attack or blood clot. However, if the pain is intermittent and not severe, it could be musculoskeletal in nature. I recommend taking Tablet Acetaminophen 500mg for pain relief. You can take 1 tablet every 6 hours as needed for chest and leg pain. Make sure to rest and avoid any strenuous activities until the pain subsides."

I've been feeling these twitching sensations in my chest for about 11.5 months now. It's like a really minor shock or spasm right in the center but a bit below my chest, and they last for less than a second. It used to happen less often, but in the last few days, it's been like 5 or 6 times a day, if not more. I've never felt anything like this before. I should probably mention I smoke, but not too heavily, and I've decided to quit after feeling these twitches. I used to go to the gym regularly before I quit a month ago, and I don't think I had this issue when I was lifting weights. I've also noticed that these twitches happen more if I haven't eaten or slept for a while, though that might just be a coincidence. It's stressing me out and making me really uncomfortable. Any ideas on what could be causing this or what I should do?
