A 40 year old man was admitted to the hospital emergency with sudden onset of the symptoms and signs of severe left ventricular failure. Calculate the atrial rate of the patient.
Ventricular rate : 1500/10 = 150 ECG shows HR of 150/min with normal axis. Saw tooth waves are noted with 2:1 AV block. Ventricular rate is 150/min therefore the atrial rate would be 300/min.
