Ventricular Premature Complexes Ventricular Premature Complexes, also known as ventricular ectopic beats are recognized in the ECG as bizarre QRS complexes not preceded by a P wave and

Sinus Bradycardia on ECG Sinus bradycardia on ECG is characterised by regular P waves preceding every QRS complex, at a rate below 60 per minute. P wave originating

U wave on ECG U wave on ECG occurs after the T wave and is usually seen in the mid precordial leads. In hypokalemia, T wave becomes flattened
