A combination of the Q wave, R wave and S wave, the “QRS complex” represents ventricular depolarization. This term can be confusing, as not all ECG leads contain all three of these waves ...

1a). The electrical events during the action potential, including initial firing (depolarization, corresponding to the QRS complex in the ECG) and subsequent return to the resting state ...

A 76-year-old woman presents with a persistently rapid heart rate that she attributes to her pacemaker. What does the ECG ...

Complex: The combination of multiple waves grouped together. The only main complex on an ECG is the QRS complex. Point: There is only one point on an ECG termed the J point, which is where the QRS ...

The goal of ECG interpretation in athletes is to classify the ECG as: (1) ‘normal’—no further evaluation needed or (2) ‘abnormal’—further evaluation needed. Normal ECGs include common, ...

The ECG findings presented as normal in athletes were established by an international ... The QRS rate for junctional rhythms is typically less than 100 beats/min, and the QRS complex usually narrow ...

Their innovative model, called ECG-LM, leverages the power of large language models (LLMs) to interpret complex ECG signals more effectively and accurately. The groundbreaking research was ...
