Q wave vs s wave
Web• Q wave reflects the depolarization of the septum with electrical vector directed right and downward (negative deflection). • R wave reflects the depolarization of apical part of ventricular myocardium with electrical vector directed left and down. • S wave represents progression of depolarization over ventricles, vector extends upward.

WebMar 29, 2024 · As leads progress across the precordium, there’s an associated R-wave progression—from V1-2 with S>R waves, to V3-4 with equiphasic R/S waves, to V5-V6 with R>S waves. Early R-wave progression has a differential ( R-WAVED mnemonic), as does late R-wave progression ( LATE mnemonic), both of which include precordial lead reversal.
WebAs two highly standardized IoT protocols, Zigbee and Z-Wave are mainly used in the smart home field. Zigbee and Z-Wave have certain differences.

WebDec 13, 2024 · However, the seismographs located beyond 142° from the epicentre, record the arrival of P-waves, but not that of S-waves. This gives clues about the solid inner core. Thus, a zone between 103° and 142° from epicentre was identified as the shadow zone for both the types of waves. Shadow Zone of P-waves and S-waves WebJul 26, 2016 · Background: Q-wave myocardial infarction (QMI) has higher mortality and lower myocardial viability than non-Q-wave myocardial infarction (NQMI), suggesting the existence of pathological Q waves reflects the worse ventricular function. The aim of the study is to determine difference in left ventricular ejection fraction (LVEF) between QMI …
