Webb30 juni 2015 · The waveform depicted here represents the arterial pressure wave of a hypertensive person with poorly compliant arteries, borrowed from Mills et al (2008), who in turn adapted it from Smith et al (2000) . It is supposed to be an aortic pulse waveform produced by applanation tonometry of the radial artery. Webb8 jan. 2024 · The classic ECG morphology of WPW syndrome is described as a shortened PR interval (often <120 ms) and a slurring and slow rise of the initial upstroke of the QRS complex (delta wave; see the image below), a widened QRS complex with a total duration greater than 0.12 seconds, and secondary repolarization changes reflected as ST …

WebbThis syndrome consists of a short PR interval (<120 msec), a wide QRS complex (>100 msec), and a slurred upstroke of the QRS (delta wave) (Fig. 2‐24). This condition is prone to reentrant SVTs. The SVT may appear as a narrow‐ or wide‐complex QRS, depending on AV node involvement and the direction of the reentry circuit.

WPW is commonly diagnosed on the basis of the electrocardiogram in an asymptomatic individual. In this case, it is manifested as a delta wave, which is a slurred upstroke in the QRS complex that is associated with a short PR interval. The short PR interval and slurring of the QRS complex are reflective of the impulse making it to the ventricles early (via the accessory pathway) witho… Webb17 feb. 2004 · 넓은 QRS complex를 나타내며 시작 부위의 slurred upstroke가 보입니다. 이것을 delta wave라고 합니다.

"WebbThe 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 is positive. This is due to the repolarization of the membrane. During ventricle contraction (QRS complex), the heart depolarizes. " - Slurred upstroke t wave
