Electrocardiogram Lead Placement
Electrocardiogram (ecg, ekg) is a print-out of the electrical forces detected by electrodes on the chest wall, as electricity travels through the heart with each heart beat. The electrodes are placed in different positions, and each position "sees" the electrical activity of the heart from its own vantage point. Abnormalities in signal detected at chest surface ...Read more
Yes: Yes, absolutely. Avr usually has inverted t-waves normally. If you invert left and right arm electrodes, avr becomes avl so now avl has inverted t waves (where as typically it does not). ...Read more
Ecg: flat t wave. Echo: ef 60%. Basis on this diagnosis is ischemia. Being asked to undergo stent placement? Should go for it or not?
ECG: It stands for electrocardiogram. It is used to measure the movement of electrical signals in the heart. When working appropriately, this enables your heart to beat and pump blood to the rest of the body. When the heart is damaged or the electrical system is malfunctioning, ECG can pick up changes. ...Read moreSee 1 more doctor answer
I know that standard ecg has 12 leads, but sometimes on some ecg I see additional strip. What is this is there a 13th lead? Could you pls explain
My ECG showed repolirisation abnormalities in lead v5 and v6 the t wave was more flat or something is this bad? I'm 23.
Non-specific: What you're describing is rather non-specific, that is, you'd have to combine the EKG findings with a thorough history and physical examination by your primary physician. They may want to, then, refer you to a cardiologist or cardiac electrophysiologist to see if the findings are significant. Call 911 if you pass out, have chest pain, severe dizziness, or sudden onset shortness of breath. ...Read more
I sometimes have a negative -t in lead 3 on ecg but other times it is positive, it changes every time what can cause this?
ECG: T wave changes as you describe are usually due to changes in vector forces from lead placement and respiration. Other variables also can come into play. In general we don't get excited by them. ...Read more
P waves: If p waves are not seen on the surface ecg, either they are not present or the vector direction of the forces doesn't produce an adequate size p wave to see in the leads available. ...Read more
