Übersetzung für 'R wave' von Englisch nach Deutsch

R wave

R-Zacke {f}med.

• An electrocardiogram (ECG) guides the image acquisition, and the resulting set of single-photon emission computed tomography (SPECT) images shows the heart as it contracts over the interval from one R wave to the next.
• To clarify, they listed the time from one heartbeat's R-wave to the next R-wave (called RR intervals) and synchronized these lists to the time of the PVC beat and averaged the values in the list.
• The R wave and the L wave are right-hand and left-hand circularly polarized, respectively.
• The ECG will show a terminal R wave in lead V1 and a slurred S wave in lead I.
• He was the first to describe the constant changes in electrocardiograms in coronary diseases in 1920, and he was the namesake of Pardee's sign, which is a takeoff of the T wave from the descending R wave that is above the electrocardiographic baseline, and Pardee's wave.

• Typically, TDBBB will be evident on an ECG and manifest as a prolongation of the QRS complex (a QRS complex completion time that exceeds 120ms), notching or slurring of the R wave, or the absence of Q waves should the TDBBB affect the left ventricle.
• Weakening of the electrical activity of the cardiac muscles causes the decrease in height of the R wave in those leads facing it.
• A pathologic Q wave is defined as having a deflection amplitude of 25% or more of the subsequent R wave, or being [...] (40 ms) in width and [...] in amplitude.
