WebThe Electrocardiogram (ECG) The ECG is a graphic record of the heart's electrical activity plotted over time. It is a very useful test which is easy to perform and readily available. This lecture is a revision of the many uses and the practical application of … WebJul 7, 2024 · P wave amplitude rarely exceeds two and a half small squares (0.25 mV). The duration of the P wave should not exceed three small squares (0.12 s). What causes P wave? The P wave indicates atrial depolarization. The P wave occurs when the sinus node, also known as the sinoatrial node, creates an action potential that depolarizes the atria.

WebOct 12, 2024 · Assess the R wave progression across the chest leads (from small in V1 to large in V6). The transition from S > R wave to R > S wave should occur in V3 or V4 . Poor progression (i.e. S > R through to leads V5 and V6) can be a sign of previous MI but can also occur in very large people due to poor lead position. WebHealthcare providers may notice small P-waves on the ECG that aren’t followed by any other waveforms.
