Pulsus paradoxus, also paradoxic pulse or paradoxical pulse, is an abnormally large decrease in stroke volume, systolic blood pressure and pulse wave amplitude during inspiration.The normal fall in pressure is less than 10 mmHg.When the drop is more than 10 mmHg, it is referred to as pulsus paradoxus. Location of maximum intensity is determined by the site where the murmur originates e.g. Almost immediately after ventricular contraction (approximately 200 msec), ventricular repolarization begins and is represented by the T-wave on the ECG.
