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.
Impaired endothelial-dependent microvascular reactivity appears to be predictive of albuminuria progression in Asian patients with type 2 diabetes (T2D) who have normal urine albumin levels at baseline, but not in those with microalbuminuria, a prospective longitudinal cohort study suggests.
Physicians’ practice patterns in managing hypertension, and their awareness of blood pressure variability, were reported in a recent study in Singapore. We discussed some of the clinical practice gaps identified by this study with author, A/Prof. Teo Boon Wee.
Results from the ASCOT-LLA study suggest that patient reports of muscle-related adverse events were more common when patients knew they were being treated with a statin. We discussed this phenomenon, known as the ‘nocebo effect’, with senior investigator, Prof. Peter Sever.
