Heart Rhythm

Hearts should have normal rhythm to their beats, but when these beats are out of synch, it causes inefficient pumping of blood. Irregular heart arrhythmias occur when the electrical signals that coordinate the heart's beats do not work properly. This can cause beats that are too fast (tachycardia), or too slow (bradycardia). Tachycardias include atrial fibrillation (AFib), supraventricular tachycardia, ventricular fibrillation, and ventricular tachycardia (VT). Bradycardias include sick sinus syndrome and conduction block. Electrophysiology arrhythmia treatments include medications, life style changes, and the EP lab interventions of catheter ablation, and implantable pacemakers or defibrillators.

JS&CD: Abnormal EKG can predict death in stroke patients

People who suffer an ischemic stroke and have an abnormality in the heart's electrical cycle at the time of emergency treatmenthave a higher risk of death within 90 days than people without abnormal electrical activity, according to research published online March 20 in the Journal of Stroke and Cerebrovascular Diseases.

PCI best for resuscitated arrest patients, despite neurologic status

When resuscitated cardiac arrest patients with STEMI are being evaluated in the emergency department, serious consideration should be given to emergent angiography and revascularization, regardless of neurologic status. These patients should be treated with the same urgency as patients with acute STEMI without cardiac arrest, according to a study in the February 3 issue of the Journal of the American College of Cardiology.
