ECGkanaler

ECGkanaler refers to the individual channels or leads used in an electrocardiogram (ECG) to record the electrical activity of the heart. An ECG machine typically uses a set of electrodes placed on the patient's body to capture these electrical signals. Each channel represents a specific view or angle of the heart's electrical depolarization and repolarization.

Standard ECGs utilize a combination of limb leads and precordial (chest) leads to create a comprehensive picture. Limb leads are placed on the arms and legs, and they provide frontal plane views of the heart's electrical activity. Common limb leads include leads I, II, III, aVR, aVL, and aVF. Precordial leads are placed on the chest in specific locations and offer a horizontal plane view of the heart. These typically include leads V1 through V6.

The signals from these electrodes are amplified and processed by the ECG machine, with each channel displaying a waveform representing the electrical events occurring in the heart over time. The patterns and characteristics of the waveforms on each channel are analyzed by healthcare professionals to diagnose various cardiac conditions, such as arrhythmias, myocardial infarction (heart attack), and hypertrophy. The number and type of ECGkanaler used can vary depending on the clinical situation, with more comprehensive monitoring potentially involving a greater number of leads.
