A year-old male patient was admitted with left sided hemiplegia caused by ischemic cerebral infarct along with hypertension. He was then placed on tab Atenolol and tab Disprin. On third day his electrocardiogram ECG revealed ventricular tachycardia. His subsequent ECG Fig. This rhythm was interrupted by a normally conducted sinus beat indicating capture beat first beat in second strip , a ventricular premature beat third beat followed by incomplete compensatory pause.
P waves are absent; P-P intervals are not applicable. Method 2:Use a heart rate table to find the rate that matches an R-R of 34 small boxes : 44 bpm. Result is between 43 and 50 bpm. The heart rate is estimated to be between 40 and 50 bpm.
Junctional rhythms are so named because the electrical impusle that starts these rhythms originates in the Atrial-Ventricular node, a. Like sinus rhythms, they have certain characeteristics to the waves originated in this area of the heart. The following figures illustrate these possibilities:.

These are passive, protective beats originating from subsidiary pacemaker cells in the AV junction usually in the Bundle of His. The pacemaker's basic firing rate is bpm; junctional escapes are protective events that occur whenever the primary pacemaker i. The ECG strip shows intermittent sinus slowing with two junctional escapes.
