Intermittent type 2 atrioventricular block can be caused by physiological factors such as exertion or pathological factors such as coronary heart disease and acute myocardial infarction, and it can be treated by general therapy, medication and installation of pacemaker.
1. Physiological factors: overwork and other factors will increase myocardial oxygen consumption, resulting in myocardial ischemia, which will cause sudden obstruction of atrial impulse conduction, and intermittent type II atrioventricular block will occur. At this time, you should pay attention to rest, regular work and rest, light diet, strengthen the nutrition, such as the frequent occurrence of this symptom or accompanied by other symptoms, it is recommended to go to a specialized hospital for further examination.
2. Pathologic factors:
(1) Coronary heart disease: if the patient’s coronary artery stenosis, it will cause myocardial ischemia, atrioventricular node area blood supply obstacle, thus appearing type II atrioventricular block. At this time, mainly for coronary heart disease to give: ① nitrate lipid preparations, such as: nitroglycerin, isosorbide nitrate, etc.; ② β-blocker, such as: metoprolol, bisoprolol, etc.; ③ ACEI, such as: perindopril, enalapril, etc.. If the symptoms are serious, drugs such as isoprenaline can be given intravenously, and pacemaker can be installed at the same time.
(2) Acute myocardial infarction: Acute myocardial infarction will lead to myocardial ischemia, which will result in type II atrioventricular block. At this time, absolute bed rest, oxygen, morphine analgesia, aspirin enteric tablet and clopidogrel sulfate tablets anti-platelet, if possible, it is appropriate to install a temporary pacemaker.
Intermittent type 2 atrioventricular block is mostly due to organic damage, it is recommended to go to a specialized hospital in a timely manner, under the guidance of a professional doctor for further examination and treatment.
