WebHeight of R wave: maximum, 0.9 mV No depression or elevation Can be positive, negative, or biphasic—most often positive Maximum amplitude: 0.3 mV Width: 0.12 to 0.18 sec at normal heart rate (range, 0.07–0.20 sec); varies with heart rate (faster rates have shorter Q-T intervals and vice versa) WebThe T wave follows the S wave, and in some cases, an additional U wave follows the T wave. To measure the QRS interval start at the end of the PR interval (or beginning of the Q wave) to the end of the S wave. Normally this interval is 0.08 to 0.10 seconds.

WebThe height of the U-wave is typically one-third of the T-wave. Its first half is steeper than its second half. U-wave inversion is rare but when seen, it is a strong indicator of pathology, … WebThis leads to a significant elevation in the height of the R wave in V5/V6 and depth of the S wave in V1/V2. LVH is usually accompanied by other features on the ECG including T wave inversion and ST depression in the lateral leads (I, aVL, V5, V6). These changes are sometimes referred to as the ‘left ventricular strain pattern’. WebThe normal T wave should measure about one-quarter to one-third of the magnitude of the R wave in leads with predominant R waves.

WebAn R wave in lead V 1 of up to 26 mm may be normal in a term newborn. 1 Right precordial R wave amplitude rapidly decreases in the first week of life28 and undergoes further reduction later in life. Conversely the R wave in lead V 6 may be nearly absent in a term newborn but increases gradually from birth to adolescence ( Figures 28-4 to 28-6 ).

WebThe R wave amplitude tends to be larger in leads V1 and V 2 at superior and leftward locations. As the site of origin shifts to the right or inferiorly, there is a trend toward lower right precordial R wave amplitude and a shift in the precordial transition zone to the left.
