All the important intervals on this recording are within normal ranges. 1. P wave: upright in leads I, aVF and V3 - V6; normal duration of less than or equal to 0.11 seconds Example #2: Old inferior Q-wave MI; note largest Q in lead III, next largest in aVF, and smallest in lead II (indicative of right coronary artery occlusion). True posterior MI. ECG changes are seen in anterior precordial leads V1-3, but are the mirror image of an anteroseptal MI: upwards deflection in AVF, since it is going towards the AVF+ lead.
Normal 12-Lead EKG/ECG Values; Wave/Interval Values; P Wave: Amplitude: 2-2.5 mm high (Or 2.5 squares) Deflection: + in I, II, AVF, V2-V6 Duration: 0.06 - 0.12 sec PR Interval A simple algorithm is presented to determine the cardiac axis from si and aVF. Figure HE.12 Reference axes and leads sl-III. Calculation Algorithm for Cardiac Axis. An example illustrating the calculation of the cardiac axis from ECG leads si and aVF is shown in Figure HE.13.
Lead aVF negative.The axis will be oriented negatively past 0°. Left axis deviation ~ -30° ECG#5 : Lead I negative. Lead aVF positive.
Lead aVF negative.The axis will be oriented negatively past 0°. Left axis deviation ~ -30° ECG#5 : Lead I negative. Lead aVF positive. 2015-10-23 2020-05-07 1. ECG: Ventricular and atrial hypertrophy with prominent septal depolarization as evidenced by Q waves in inferior leads (II, II and aVF) as well as the lateral leads (I, aVL, V5 and V6.) 2. Given these symptoms, near-syncopal episode, cardiac murmur and ECG findings one should suspect the diagnosis of Hypertrophic cardiomyopathy (HCM). 3.

Right bundle branch block persists. The T wave negativity in lead aVF has disappeared and the amplitude of the q wave has decreased. T wave negativity in lead III persists.

2016-05-19 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.The last half of the T wave is referred to as the relative refractory period or vulnerable period.The T wave contains more information than the QT interval.
