J-point is the point at which the QRS complex meets the ST wave. ST segment elevation with an upward convexity is usually benign, especial.
“ Interpreting an ECG The ECG (electrocardiogram) is divided into three main sections: the P wave, the QRS complex, and the T wave. During the phase known as the P wave, the atria contract. The QRS complex is the ventricular contraction, and the T...
This rhythm reflects Mobitz Type I AV block or Wenkebach, which is not usually secondary to structural abnormalities when the QRS complex is narrow, but is vagally mediated instead. Increased vagal tone occurs in the young or the athletic with frequencies ranging from 2 to 10%. No treatment is necessary unless the patient is symptomatic.
EKG basics PR Interval: From the start of the P wave to the start of the QRS complex PR Segment:From the end of the P wave to the start of the QRS complex QT Interval: From the start of the QRS complex to the end of the T wave QRS Interval:From the.
