Sinus arrhythmia is mostly triggered by physiologic factors and is not related to complete right bundle branch block.
Sinus arrhythmia is a common clinical arrhythmia, mostly seen in normal adolescents, mainly associated with smoking and drinking alcohol, strenuous exercise, drinking strong tea, mainly triggered by physiological factors of this disease, usually do not need treatment.
Complete right bundle branch block is a type of bundle branch block. Right bundle branch block is common in coronary heart disease, ventricular septal defect, pulmonary heart disease, rheumatic heart disease, etc. It can also be seen in normal people. Because this disease does not affect the pumping energy supply of the heart and does not affect hemodynamics, it is mostly without clinical symptoms, and if there are symptoms, other diseases are mainly considered to be the cause.
Although sinus arrhythmia and complete right bundle branch block have different pathogenesis, they generally have no effect on hemodynamics and usually have no clinical discomfort, so they can be left untreated with regular observation.
If they are accompanied by cardiac discomfort, it is necessary to seek medical treatment in time to avoid delays.
