Depolarization occurs in the four chambers of the heart: both atria first, and then both ventricles. 1. The sinoatrial (SA) node on the wall of the right atrium initiates depolarization in the right and left atria, causing contraction, which corresponds to the P wave on an electrocardiogram. WebThe wavelength of the cardiac impulse is defined as the distance travelled by the depolarization wave during the refractory period (wavelength of refractoriness) ( Smeets … long snouted pipefish

The T wave can be described by its symmetry, skewness, slope of ascending and descending limbs, amplitude and subintervals like the T peak –T end interval. [1] In most leads, the T wave is positive. This is due to the repolarization of the membrane. During ventricle contraction (QRS complex), the heart depolarizes. See more In electrocardiography, the T wave represents the repolarization of the ventricles. The interval from the beginning of the QRS complex to the apex of the T wave is referred to as the absolute refractory period. … See more The refractory period of cardiac muscle is distinct from that of skeletal muscle. Nerves that innervate skeletal muscle have an extremely short … See more Both the abnormalities of the ST segment and T wave represents the abnormalities of the ventricular repolarization or secondary to abnormalities in ventricular depolarisation. Inverted T wave Inverted T wave is … See more Normally, T waves are upright in all leads, except aVR, aVL, III and V1 leads. Highest amplitude of T wave is found at V2 and V3 leads.
