P Wave - The Definitive Guide Biology Dictionary
WebAs the current passes through the heart muscle, the muscle reacts by flexing. That causes your heart to squeeze and pump blood. That electrical current is detectable with a diagnostic test called an electrocardiogram (ECG or EKG). With PEA, your heart does have a detectable electrical current, but your heart isn’t strong enough to pump blood ... WebThus, the excitation-contraction coupling process begins with signaling from the nervous system at the neuromuscular junction ( Figure 10.3.1) and ends with calcium release for muscle contraction. Figure 10.3.1 – Motor End … WebThe P-wave, PR interval and PR segment. ECG interpretation traditionally starts with an assessment of the P-wave.
