What does P - wave represent in ECG?

The P wave represents electrical activity (in volts) that causes cardiac muscle contraction in the atria – the upper two heart chambers. When a P wave definition says it represents atrial contraction, this is not entirely incorrect. What a P wave depicts is the voltage (over time) that specifically triggers atrial … Ver mais A P wave on an electrocardiogram represents a phase of electrical activity that causes the atria of the heart to contract. The P wave is a summation wave – electrical activity that comes from successive signaling … Ver mais The P wave is the first wave on an electrocardiogram (ECG).
