sir.—Intermittent bradycardia, a common problem in preterm infants, develops in approximately 25% of infants of less than 32 weeks' gestation.1 The causes
He says the central bank caused a spike in short-term rates as a way of conditions such as hypokalemia, bradycardia or recent myocardial ischemia. This drug
A wide range of conditions, including ischemia, infections, inflammatory and infiltrative disorders, may cause bradyarrhythmia. The decision regarding permanent pacemaker implantation depends on the reversibility of the etiology of bradyarrhythmia. Of the two general causes of bradycardia (sinus node-mediated or heart block), sinus node bradycardia is by far the more common. Sinus Node The heartbeat is normally generated and coordinated by the heart's electrical impulse, and the electrical impulse is generated in the sinus node, a tiny nest of cells located at the top of the right atrium.
Cardiac causes include acute or chronic ischemic heart disease, vascular heart disease, valvular heart disease, or degenerative primary electrical disease. Ultimately, the causes act by three mechanisms: depressed automaticity of the heart, conduction block, or escape pacemakers and rhythms. Transient sinus bradycardia is most often caused by the increased tone in the vagus nerve, such as during sleep. The vagal nerve helps regulate the control of the heart, lungs, and digestive tract. Once the vagal tone is restored to normal, the heart rate also returns to normal, so no permanent treatment of the bradycardia itself may be required.

7 8 It is however important to identify and treat reversible causes such as hypothyroidism 9 and drug therapy. 10 11 Comorbidities such as hypertension and ischaemic heart disease are also recognised risk factors. 12 Cardiac ischaemia, particularly of the right coronary circulation, can cause sinus bradycardia and sustained complete heart block.

sinus bradyarrhythmia - impulse generation occurs in the sinoatrial node, but under the influence of the parasympathetic nervous system, the heart rate decreases to 50 beats. This condition is considered physiological for some people, for example, trained athletes. However, an ordinary person should cause concern. marijuana induced bradyarrhythmia – a benign but rare cause of syncope Abhijai Singh, MD, Kartik G, Mon Health Medical Center, Morgantown, WV Meeting: Hospital Medicine 2019, March 24-27, National Harbor, Md.

hyperkalemia) and bradyarrhythmia. CLINICAL PRESENTATION Persistent dizziness or a near syncopal event commonly causes clients to seek medical attention (Hammill, 1997). Often, noninvasive assessment can help to diagnose the problem. A change in both blood pressure and heart rate might indi cate a cardiac cause for the syncope.
