hjartslög

Hjartslög is a Swedish term that translates to "heartbeat" or "heart rhythm." It refers to the natural, rhythmic contraction and expansion of the heart muscle that pumps blood throughout the body. This rhythm is controlled by the heart's electrical system, which generates impulses that cause the heart to beat at a regular pace.

The normal resting heart rate for an adult is typically between 60 and 100 beats per minute. This rate can vary depending on factors such as age, physical activity, stress, and underlying health conditions. A consistently abnormal heart rhythm is known as an arrhythmia.

Arrhythmias can manifest in various ways, including a heart beating too fast (tachycardia), too slow (bradycardia), or irregularly. Some arrhythmias are harmless, while others can be serious and require medical attention. Symptoms of an arrhythmia can include palpitations, shortness of breath, dizziness, chest pain, or fainting.

The diagnosis of hjartslög abnormalities often involves an electrocardiogram (ECG or EKG), which records the electrical activity of the heart. Other diagnostic tools may include Holter monitors, event recorders, or echocardiograms. Treatment for arrhythmias depends on the specific type and severity of the condition and may involve lifestyle changes, medications, or procedures like cardioversion or pacemaker implantation. Maintaining a healthy lifestyle, including regular exercise and a balanced diet, can contribute to a healthy heart rhythm.
