"WebMaximal positive ECG deflection occurs in lead I when a wave of depolarization travels parallel to the axis from the right to left arm. If a wave of depolarization heads away from the left arm, the deflection is negative. Also, by these rules, a wave of repolarization moving away from the left arm is recorded as a positive deflection. Similar ... " - Ekg deflection

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. WebFeb 1, 2024 · When electrical impulse travels towards or away from an ECG lead, a deflection from the baseline is recorded on the ECG strip, that is called a wave. Whenever there is electrical activity on the heart, there will be some deflections on the ECG strip. The straight line, in other words no deflection from the baseline means a dead heart or …

WebNov 8, 2024 · In a normal EKG, the P-wave precedes the QRS complex. It looks like a small bump upwards from the baseline. The amplitude is normally 0.05 to 0.25mV (0.5 to 2.5 small boxes). Normal duration is 0.06-0.12 seconds (1.5 to 2.75 small boxes). The shape of a P-wave is usually smooth and rounded. WebJun 2, 2024 · To do this we need to understand the basic 6 leads and their geometry. The EKG waveform comes from a measurement of surface voltages between 2 leads. A wave that is travelling towards the positive (+) lead will inscribe an upwards deflection of the EKG; conversely a wave traveling away from the positive lead will inscribe a downward …
