Cardiac Arrhythmias
摘要
A 64-year-old male with a history of hypertension and chronic obstructive pulmonary disease was admitted to the intensive care unit with acute infective exacerbation of his pulmonary condition and type 2 respiratory failure. He was doing reasonably well with standard medical treatment and non-invasive ventilator support until he suddenly became hypotensive on his third hospitalization day. The monitor showed an irregularly irregular narrow QRS complex tachycardia with a ventricular rate of 156 per minute and blood pressure of 76/40 mmHg, pulse oximetry reading of 80% on fractional inspiratory oxygen 0.4.
