WebAug 6, 2024 · A Q wave is a negative deflection before the R wave. The Q wave indicates the interventricular septum's usual left-to-right depolarization. Small 'septal' Q waves are often seen in the left-sided leads (I, aVL, V5 and V6) In most leads, little Q waves are typical. As a typical variation, deeper Q waves (>2 mm) may be found in leads III and aVR. WebThe P-wave, PR interval and PR segment. ECG interpretation traditionally starts with an assessment of the P-wave. The P-wave reflects atrial depolarization (activation). The PR interval is the distance between the …

WebThe contraction of cardiac muscle is regulated in a centre located in the right atrium known as the sinus node. Cardiac muscle cells have a special property: they spontaneously depolarize at various rates (i.e. the charge of their membranes changes at a given rate without external stimuli). The resultant coordinated contraction leads to the ECG ... WebThe P, R, and T-waves are above the base line and are known as positive waves. The Q and S-waves are below the base line and are known as negative waves. The P-wave is of atrial origin, while the Q, R, S, and T-waves are of ventricular origin. (a) The P-wave indicates atrial depolarisation.
