Intermittent second-degree type I atrioventricular block is a type of atrioventricular block that is due to delayed or interrupted electrical conduction impulses from the atria to the ventricles. It can occur in healthy normal people and athletes, and is also seen in patients with organic heart disease. It can be clinically asymptomatic or present with a missed beat or other manifestations. An electrocardiogram is usually chosen, and clinical treatment should be tailored to the cause.
The disease can occur in young people with high vagal tone or high physical fitness athletes, in which case there are no clinical symptoms and no special treatment is needed, and the prognosis is good. The prognosis is good. The patient should eat a healthy diet with plenty of fruits and vegetables, take appropriate physical exercise, and maintain a healthy body weight.
For patients with underlying heart disease, such as myocarditis, acute myocardial infarction, endocarditis, hyperkalemia, often manifested as bradycardia, missed beats, and if there is a slowing of the heart rate affecting the blood supply, it will be manifested as fatigue, dizziness, sweating, or even fainting, resulting in a poor clinical prognosis.
A 12-lead electrocardiogram is often used in clinical practice. For patients with bradycardia or with hypovolemia, pacemakers and atropine should be applied selectively as prescribed by the doctor.
Note: If cardiac discomfort occurs, you should seek medical attention in time to avoid delays.
