EKGkurven

EKGkurven, also known as electrocardiogram waveforms, represent the electrical activity of the heart recorded over time. These waveforms are crucial diagnostic tools in cardiology, providing insights into the heart's rhythm, rate, and overall electrical health. The standard EKG recording displays several distinct waves and intervals: the P wave, QRS complex, and T wave.

The P wave signifies atrial depolarization, the electrical activation of the atria, which precedes atrial contraction. Following the P wave is the PR interval, representing the time it takes for the electrical impulse to travel from the atria through the AV node to the ventricles. The QRS complex, typically the most prominent part of the EKGkurven, denotes ventricular depolarization and precedes ventricular contraction. It consists of the Q wave (the first downward deflection), the R wave (the first upward deflection), and the S wave (the first downward deflection after an R wave).

The ST segment, the flat line between the QRS complex and the T wave, represents the period when the ventricles are fully depolarized. Finally, the T wave indicates ventricular repolarization, the electrical recovery of the ventricles before the next heartbeat. Abnormalities in the shape, duration, or timing of these EKGkurven can indicate a wide range of cardiac conditions, including arrhythmias, myocardial infarction (heart attack), and hypertrophy. Interpretation of EKGkurven requires specialized knowledge and is performed by trained medical professionals.
