Hertz

(hɜːts; German hɛrts)
n
1. (Biography) Gustav (ˈɡʊstaf). 1887–1975, German atomic physicist. He provided evidence for the quantum theory by his research with Franck on the effects produced by bombarding atoms with electrons: they shared the Nobel prize for physics (1925)
2. (Biography) Heinrich Rudolph (ˈhainrɪç ˈruːdɔlf). 1857–94, German physicist. He was the first to produce electromagnetic waves artificially

hertz

(hûrts)
A unit used to measure the frequency of vibrations and waves. One hertz is equal to one cycle per second. Radio waves are usually measured in megahertz, or millions of hertz.

Microvolt T-wave alternans for risk stratification of cardiac events in ischemic cardiomyopathy: A meta-analysis.
Especially, the determination of T-wave end is the paramount problem to be solved.
The T-wave abnormality was considered when there was inversion of T waves, flat T waves or abnormal tall T waves of 10 mm in chest leads and mid-precordial leads (Exceeding 60% of the height of R-wave.
At the lowest serum potassium levels the T-wave becomes a notch on the upstroke of a giant U-wave, as occurs here in the ECG of this woman with a serum potassium of 1.
Peri-procedure, pronounced ST elevation suggestive of myocardial ischaemia manifested on the electrocardiogram lasting for four hours post-procedure, upon which the athlete developed deep and diffuse inferolateral T-wave inversion.
Results: Biphasic T-wave inversion was seen most commonly in leads v2-v3 in 26 (26%) patients, and in leads v2-v4 in 25 (25%) patients.
2: STJ depression [greater than or equal to] 1 mm but < 2 mm and ST segment horizontal or downward sloping in any of leads V1, V2, V3, V4, V5), T-wave changes (Minnesota code 5.
Objective: The aim of this study was to evaluate influence of noise, T-wave jitter and electrocardiographic (ECG) signal parameters on sensitivity of T-wave alternans (TWA) detection methods.
Non-invasive T-wave alternans (TWA) test: The TWA test measures beat-to-beat variability in your heart using an electrocardiogram (ECG) to predict your risk of sudden cardiac death.
Computers can detect the abnormality, called T-wave alternans, during an electrocardiogram, a recording of the heart's electrical activity.
Using electrocardiograms (ECGs) taken every two weeks during late 2000 and early 2001, the team analyzed four key indicators of heart function and condition: QT interval duration (the total time from ventricular depolarization to complete repolarization) and T-wave amplitude, complexity, and variability of complexity (all indicators of normal ventricular repolarization).
SAN FRANCISCO -- The search is on for a more reliable predictor of patients with heart failure who are likely to benefit from an implantable cardioverter defibrillator, and T-wave alternans shows the most promise, Dr.
