ECG Interpretation

説明 ECG Interpretation

Site Editorial Commentary：This app briefly elaborate of ECG irregularities with waveform and description.

Electrocardiography (ECG or EKG) is the process of recording the electrical activity of the heart over a period of time using electrodes placed on the body. This non-invasive test provides valuable insights into the heart's function and can help diagnose a variety of cardiac conditions.

A typical ECG tracing displays a repeating cycle of distinct electrical entities: the P wave (representing atrial depolarization), the QRS complex (indicating ventricular depolarization), and the T wave (reflecting ventricular repolarization). Understanding these components is crucial for accurate ECG interpretation.

The ECG is traditionally interpreted methodically to ensure no significant findings are overlooked. This app helps you learn and practice systematic ECG analysis.

In a healthy individual, the normal heart rate typically ranges from 60 to 100 beats per minute. A heart rate below 60 bpm is classified as bradycardia, while a rate exceeding 100 bpm is considered tachycardia. It's worth noting that some highly trained Athletes may naturally exhibit a resting heart rate below 60 bpm.

The heart's electrical axis represents the general direction of the ventricular depolarization wavefront (or mean electrical vector) within the sagittal plane, specifically focusing on the limb leads and augmented limb leads. Deviations from the normal axis can indicate underlying heart conditions.

It's important to be aware that an ECG tracing can be influenced by patient movement. Rhythmic motions such as shivering or tremors can sometimes mimic cardiac dysrhythmias, potentially leading to misinterpretations. This app provides information to differentiate between artifacts and true cardiac events.
