Herzfrequenz und Blutdruck — version history

At rest, a full circulatory cycle takes just 20 seconds. Blood travels from the heart to the lungs and back in 6 seconds, to the brain in 8 seconds, and to the tips of the toes in 16 seconds. In this version: - Bug fixes - Performance improvements

Purkinje fibers are the fastest conductors in the heart: they transmit electrical signals at speeds of up to 4 m/s, ensuring the synchronous contraction of the ventricles. Without them, the heart would function like a "loose pump." In this version: - Bug fixes - Performance improvements

The atria contract slightly before the ventricles (by 0.1–0.2 seconds) to ensure they have time to push blood downward. If this order is disrupted, atrial fibrillation occurs—chaotic contractions that reduce pumping efficiency by 20–30%. In this version: - Bug fixes - Performance improvements

A healthy heart can function for at least 150 years. In this version: - Bug fixes - Performance improvements

Depending on body type, the heart may hang vertically in the chest (in thin, tall people), obliquely (in people of average height with a normal build), or lie horizontally (in overweight people with a broad chest). In this version: - Bug fixes - Performance improvements
