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.
Normal Intervals P-R interval = - sec - 5 small squares) QRS width = - sec - 3 small squares) Q-T interval - sec * The PR interval should really be referred to as the PQ interval; however it is commonly referred as the PR interval
Sinus arrhythmia often accompanies sinus bradycardia, but the P waves have a normal morphology unless atrial disease is present. (See "Normal sinus rhythm and sinus arrhythmia"). A PR interval of up to is normal in sinus bradycardia.

bklynmed: Ventricular Tachycardia (VT) often results in haemodynamic compromise due to minimal ventricular filling time and the absence of atrial kick. VT also has a tendency to transition into ventricular fibrillation. The causes of VT can include myocardial ischaemia, cardiac drug toxicity and electrolyte imbalance. Pulseless VT requires urgent defibrillation. Regularity: Regular, but sometimes can be slightly irregular. Rate: 100-250bpm P waves: None, or not associated with the QRS…
