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. The T wave can be described by its symmetry, skewness, slope of ascending and descending limbs, amplitude and subintervals like the T peak –T end interval. [1] In most leads, the T wave ...
T-wave alternans and prolonged QT interval in a male patient found to be in a narrow-complex tachycardia and ruled in for an acute myocardial infarction.Administered Ibutilide and converted to sinus rhythm but subsequently had an episode of Torsades de Pointes which required DC cardioversion back into sinus rhythm.
P=P wave, PR=PR interval, QRS=QRS complex, QT=QT interval, ST=ST segment, T=T wave Wiggers with jugular venous waveform Wiggers diagram with mechanical (echo), electrical (ECG), and aortic pressure (catheter) waveforms, together with an in-ear dynamic pressure waveform measured using a novel infrasonic hemodynography technology, for a patient ...
The definition of poor R wave progression (PRWP) varies in the literature. It may be defined, for example, as R wave of less than 2–4 mm in leads V 3 or V 4 and/or presence of a reversed R wave progression, which is defined as R in V 4 < R in V 3 or R in V 3 < R in V 2 or R in V 2 < R in V 1, or any combination of these.

First described by Hein J. J. Wellens and colleagues in 1982 in a subgroup of people with unstable angina, [2] it does not seem to be rare, appearing in 18% of patients in his original study. A subsequent prospective study identified this syndrome in 14% of patients at presentation and 60% of patients within the first 24 hours.

Diagnosis is based on an ECG showing ST-segment depression at the J-point of 1 to 3 mm in leads V1 to V6, with tall and symmetrical T waves. [1] The ST-segment is upsloping and there is also often ST-segment elevation of 0.5 to 2 mm in lead aVR. [1] [2] The QRS complex is either normal or slightly wide. [1]
The two-time defending champion Chiefs are one step closer to completing a three-peat, which has never been done in the Super Bowl era. They will have to go through the surging Bills in the AFC ...
