Slow heartbeat can make people feel extremely tired, physically weak, and mentally sluggish. More severe bradycardia can also cause patients to repeatedly faint, posing a greater risk. In addition, it can also cause ischemic diseases, resulting in long-term insufficient blood supply to the brain, causing severe ischemia of the kidneys, heart, and other organs, which can be very harmful. It is necessary to promptly identify the cause and treat it accordingly.
1. Easy fatigue: Symptoms such as weakness, headache, and mental sluggishness may occur. There are many reasons for bradycardia, and patients are not only prone to fatigue, but also have other symptoms that are directly related to the primary disease. If it is caused by heart and blood vessel diseases, the condition is often more severe, and the symptoms will continue to worsen. If not treated promptly, it may be life-threatening.
2. Syncope: When the heartbeat is below 40 beats per minute, patients may experience symptoms such as dizziness, palpitations, chest tightness, and shortness of breath. In severe cases, they may suddenly faint. Patients often experience transient blindness during activities and have to rest. Exclude possible causative medications. Patients can appropriately use atropine or isoproterenol to improve heart rate. If patients repeatedly faint, it is best to implant a cardiac pacemaker.
3. Ischemic diseases caused by bradycardia: Long-term slow heart rate can cause cerebral insufficiency and ischemic heart disease, and renal ischemia can lead to renal failure. Therefore, long-term bradycardia must be taken seriously, requiring electrocardiogram examination combined with a history of bradycardia. Effective drugs should be used to increase the slow heart rate and improve blood supply to vital organs.
