Heart st waves

Web3 de jun. de 2024 · An ECG measures the timing and duration of each electrical phase in the heartbeat. The signals are shown as waves on an attached computer monitor or printer. An ECG labels the heart's electrical signals as five waves using the letters P, Q, R, S and T. Waves Q through T show the electrical activity in the heart's lower chambers (ventricles). • The normal ST segment has a slight upward concavity. • Flat, downsloping, or depressed ST segments may indicate coronary ischemia. • ST elevation may indicate transmural myocardial infarction. An elevation of >1mm and longer than 80 milliseconds following the J-point. This measure has a false positive rate of 15-20% (which is slightly higher in women than men) and a false negative rate of …
