Hi,

Thanks for writing in.

An Old Lateral MI would show large 'Q' waves (first negative wave in a QRS complex) in your lateral leads ie leads V5 and V6.

Sometimes it can even show decapitation of 'R' waves in leads V5 and V6 and poor R wave progression i.e. the generally the R wave increases in size from V1 to V6 but with a lateral MI it may not increase in size as expected.

Hope I have answered your query. If you have any further questions I will be happy to help

Regards
Dr. Om Lakhani

Hi,

Well that depends on the changes on the ECG. Depends on what kind of abnormal rhythm you see on the ECG. The best thing .. to consult your healthcare professional ASAP when you see such ECG changes.

I often have an irregular heartbeat during the course of the day (5 to 6 times). I can feel gas moving around in my system almost everytime this occurs. I often have rapid heartbeats which are relieved by passing . I was hospitalized before because I thought tI was having a heart attack but after thorough testing (ekg, ultrasound, stress test, wearing a heart monitor at home) they found nothing. What could be a possible avenue that I can pursue to finally get rid of this or at least be able to treat it.

I am a man 40 years old. I walk 9.1 kms every week. Every time I go to the doctor he always tell me that my heart is smooth. When I tried ECG it was perfect. However after I masturbate I get chest pressures. After 24 hours everything becomes normal again and I become a healthy man.

Is there anything wrong that I get chest pressure after I masturbate?
