What does electrocardiogram show sinus bradycardia mean? Sinus bradycardia must first conform to sinus, and any rhythm originating from sinus node is called sinus rhythm. Two conditions are met. The first is that the P wave in leads I, II and aVF is vertical and the aVR is inverted. Second, the P-R interval is 0. 1.2 ~ 0.20 seconds.
When the sinus rhythm is less than 60 beats per minute, it is called sinus bradycardia. Sinus bradycardia can be seen in healthy adults, especially athletes, the elderly and during sleep, as well as in organic heart diseases, such as coronary heart disease, acute myocardial infarction, myocarditis, cardiomyopathy and sick sinus syndrome.
Is sinus bradycardia dangerous? Sinus bradycardia is mostly not dangerous, but if the heart rate of patients with organic heart disease is too slow, the cardiac output will drop obviously, which will affect the blood supply of important organs such as heart, brain and kidney, and even lead to sinus arrest when syncope occurs, which is dangerous to human body. Therefore, the risk of sinus bradycardia is not dangerous, most of them are not dangerous, mainly depending on whether it affects hemodynamics.
Sinus bradycardia If the electrocardiogram is sinus and the heart rate is lower than 60 beats per minute, it means sinus bradycardia. The sinus heart rate of normal people is 60- 100 beats/min. Sinus bradycardia itself generally does not need treatment, and it can be seen in normal adults, especially athletes and the elderly. But in some organic heart diseases, there are also sinus bradycardia, which can be seen in coronary heart disease, acute myocardial infarction, myocarditis, cardiomyopathy and sick sinus syndrome. Therefore, if sinus bradycardia occurs, you should seek medical attention.
Can sinus bradycardia die? Most sinus bradycardia has no important clinical significance and generally does not lead to death. However, when the function of sinoatrial node is seriously damaged, resulting in severe sinus bradycardia, extremely slow heart rate, obvious symptoms, and even syncope symptoms, sinus arrest can suddenly occur under the condition of poor drug treatment, leading to death. Therefore, when the heart rate is too slow, sinus bradycardia leads to insufficient blood supply and syncope symptoms, it is recommended to seek medical advice and install a permanent artificial pacemaker if necessary to prevent sinus arrest.
