ecg

[SHORTY865]

everyonce and a while i get this stabing pain in my chest and it feels like that my heart is going to jump out of my chest. sometimes i feel like passing out when i get the pain and it really hurts and lasts 10-15 mins. i had so many ecg's done and every doctor told me that they were normal but one doctor told my that my ecg wasnt normal and he showed me that the flat line dip was to long then it would be short then go to long it was a pattern. what does that mean.

If you're talking about the actual drop after the spike for the heartbeat, then you are talking about the T-wave and what you describe can be a normal variant. If you are talking about the length of the line before the next smaller spike, that is the ST Segment and represents the amount of time it takes from depolarization of the left ventricle to it's repolarization. There are many causes for this, mostly not serious, some are. You really need to have your doctor give you a better answer than it wasn't normal. This can represent damage to the heart muscle or a simple interruption in the path of the electrical signal, in either case you should make him explain his thoughts better.

I know this is vague, but I hope it helps.

Hard to say from your description, but it seems you have premature beats in some kind of a pattern (bigeminy or trigeminy). This may also explain the senstion of a jumping heart.

When you say "dip" I assume you mean the spike representing the heart beat. In some leads this may be negative, a "dip" but in most leads it's usually positive, or it goes both ways.

Maybe see a cardiologist and ask for holter testing where it can record ur heart ryhthm when u have ur chestpain and fainting spells,and when u did ur ecg did u have any symptoms at that time?
