Why does the heart beat faster sometimes? Explanations from the Medical Reality programme

In a new episode of the programme Realitatea Medicală, Nicole Păcuraru discusses palpitations: why they occur, when they are a normal phenomenon, and when they may signal a condition that requires medical investigation.

According to the discussion on the programme, the heart can beat harder or faster even without any physical exertion. Among the factors that can accelerate heart rate are caffeine, stress, lack of sleep, and anxiety. In these situations, the heart is not responding to physical effort, but rather to internal signals from the body.

In most cases, these episodes do not pose a danger. However, if palpitations occur frequently, arise whilst at rest, or are accompanied by dizziness, the situation requires medical investigation.

An important point highlighted in the programme is that the heart is highly sensitive to the body's overall state: it responds not only to physical movement, but also to emotions.
