What is ECG and how to investigate the atrium ventricular activity?
Understand the Problem
The question is asking for an explanation of ECG (electrocardiogram) and how to investigate the atrial ventricular activity, which involves understanding cardiac rhythms and possibly diagnostic methods.
Answer
ECG records heart activity using skin electrodes; P-wave shows atrial depolarization, QRS complex shows ventricular depolarization, and T-wave shows ventricular repolarization.
The electrocardiogram (ECG or EKG) is a non-invasive method that records the heart's electrical activity via electrodes on the skin. The ECG traces several waves that reflect the heart's activity: the P-wave represents atrial depolarization, the QRS complex represents ventricular depolarization, and the T-wave represents ventricular repolarization.

More Information
ECGs are crucial diagnostic tools for assessing heart rhythm, identifying cardiac abnormalities, and guiding treatment decisions.
Tips
Common mistakes include mislabeling the waves or misunderstanding their significance. Ensure correct identification of each wave and complex in the ECG.
