R wave

R waves at frequencies below ω/2 are also known as whistler modes.

Phase coordination was assessed by determining the respiratory phases of R waves which follow a reference beat.

No loss of precordial R waves.

The R wave and the L wave are right-hand and left-hand circularly polarized, respectively.

The R wave has a cut-off at ω (hence the designation of this frequency) and a resonance at ω.

Prior to 2009, this transmission had issues caused by a very weak 3,5,R wave plate, which made this transmission prone to failure in GM products.

It also makes the electrocardiographic diagnosis of LVH more complicated, because both may cause a large R wave in lead aVL.

LAHB may be a cause of poor R wave progression across the precordium causing a pseudoinfarction pattern mimicking an anteroseptal infarction.

In biomedical engineering, the maximum amplitude in the R wave is usually called "R peak amplitude", or just "R peak".

The electrocardiogram will show tall, peaked T waves (often larger than the R wave) or can degenerate into a sine wave as the QRS complex widens.

An R wave follows as an upward deflection, and the S wave is any downward deflection after the R wave.

Timing the shock to the R wave prevents the delivery of the shock during the vulnerable period (or relative refractory period) of the cardiac cycle, which could induce ventricular fibrillation.

A "window" may be set which discards data from R to R intervals which deviate from some amount from the patient's average R to R wave duration.

On an ECG the heart rate is measured using the R wave to R wave interval (RR interval).

Looking at the precordial leads, the r wave usually progresses from showing a rS-type complex in V with an increasing R and a decreasing S wave when moving towards the left side.

The ECG will show a QS or rS complex in lead V1 and a monophasic R wave in lead I. Another normal finding with bundle branch block is appropriate T wave discordance.

Poor R wave progression is commonly attributed to anterior myocardial infarction, but it may also be caused by left bundle branch block, Wolff-Parkinson-White syndrome, right and left ventricular hypertrophy as well as by faulty ECG recording technique.

LF and HF power (LF, HF) are computed in milliseconds such that they correspond to the standard deviation of the LF and HF band-passed RR tachogram (times between R waves in milliseconds).

They used an apparatus named 'coincidence analyzer' which was able to determine the absolute time delay of the onset of inspiration precisely after the preceding R wave - see Footnote 1 - and which calculated the 'coupling rate' on the basis of the distribution of the detected time lags.

The Cornell voltage criteria for the ECG diagnosis of LVH involve measurement of the sum of the R wave in lead aVL and the S wave in lead V. The Cornell criteria for LVH are:

In the electrocardiogram, the time of the onset of the intrinsicoid deflection, also referred to as the R wave peak time, is measured from the beginning of the QRS complex to the peak of the R wave.
