Bradycardia is having a heart rate of <60 beats/minute that may not affect the hemodynamic status of some patients.
A heart rate that is
inadequate for the patient's current condition and may not be able to
support life is a clinically significant bradycardia.
Bradycardia can be caused by problems in the sinoatrial node, problems in the conduction pathways of the heart, metabolic problems or heart attack/disease that caused damage to the heart.
The different types of bradycardia are sinus bradycardia, sick sinus syndrome, tachycardia-bradycardia syndrome, hypersensitive carotid sinus syndrome, sinus pause/arrest, sinoatrial node exit block and atrioventricular block.
Intraoperative methylprednisolone does not appear to significantly prevent the incidence of death, cardiac arrest and other injuries in neonates undergoing cardiac surgery with cardiopulmonary bypass, according to a recent study.
Treatment with low-to-standard dose dual combination therapy of blood pressure (BP)-lowering drugs is more effective than standard-dose monotherapy and does not increase withdrawals due to adverse events, a recent study has shown.
Untreated white coat hypertension (WCH), but not treated white coat effect (WCE), may increase the risk for cardiovascular events and all-cause mortality, suggest the results of a systematic review and meta-analysis. Out-of-office blood pressure (BP) monitoring is thus important in the diagnosis and management of hypertension.
Risk factors for 1-year mortality in heart failure (HF) patients significantly differ between those with and without chronic kidney disease (CKD), especially with regard to the use of beta-blockers or diuretics at discharge, according to a study. This suggests that these patients may benefit from individualized therapies.
