Sudden cardiac death recorded in an 82-year-old woman with heart failure who was wearing a portable monitor (Holter tape) that measures the continuous electrocardiogram. At 15:42:49, the rhythm consists of beats originating from the normal sinus node pacemaker (N), with two isolated premature ventricular ectopic beats arising from an abnormal site in the ventricles (V). The trace at 16:05:55 shows an alternation of normal sinus beats with ventricular ectopic beats and three sequences of three consecutive ventricular ectopic beats, nonsustained ventricular tachycardia (NSVT). At 19:13:53, the record is initially similar to the record at 16:05:55, but there is a more prolonged nonsustained ventricular tachycardia, followed by a sinus beat, and then a sustained ventricular tachycardia (VT) that leads to sudden death. The trace (recording from patient no. 52) is taken from the Sudden Cardiac Death Holter Database of the National Institutes of Health Research Resource for Complex Physiologic Signals (www.physionet.org).
