A high-quality 12-lead ECG
is more useful in the clinical setting than individual rhythm strips.
Studies by Stewart et al have already confirmed a close relationship between electrocardiographic changes and more extensive PW infarction in terms of standard 12-lead ECG
and the more extensive 15-lead ECG.
The basic 12-lead ECG
, in some form, will continue to be of significant diagnostic value for the foreseeable future.
The standard 12-lead ECG
requires that 10 ECG leads be attached to the patient's body.
Here, too, the smartphone-assessed heart rate is just as accurate as clinically measured heart rate, with sensitivity exceeding 99% for QRS detection (and thus R to R intervals), putting it on par with the 12-lead ECG
, according to Dr.
The all but one of the subjects had no clinical evidence (history, 12-lead ECG
, 24-hour Holter ambulatory monitoring, chest X-rays, echocardiography) of cardiovascular impairments.
The AHA panel issued the update in part to address recommendations from the European Society of Cardiology and the International Olympic Committee, each of which has promoted the routine use of 12-lead ECG
in preparticipation sports screening.
Other topics include 12-lead ECG
interpretation and pharmacologic and non-pharmacologic treatments.
The PRIME ECG system uses 80 leads to provide significantly more information about the electrical activity of the heart than can be obtained through use of the conventional 12-lead ECG
, a standard of care virtually unchanged for over 60 years.
The researchers used data from the 12-lead ECG
recordings of these patients, as analyzed by the Cornell product equation and by Sokolow-Lyon voltage to calculate left ventricular size.
Patients without ST-elevation on standard 12-lead ECG
were selected and evaluated for isolated right-sided ST-elevation.
The CV screening includes a physical exam, family and personal history, and a 12-lead ECG
