ECG criteria of multifocal atrial tachycardia Heart rate greater than 100 beats per minute. Discrete P waves with at least three different morphologies (including the normal sinus P wave). P waves which are separated by isoelectric intervals. P-P intervals‚ P-R duration‚ and R-R intervals which vary. The best initial treatment for multifocal atrial tachycardia is treatment of the underlying cause and correction of electrolyte abnormalities (e.g.‚ hypokalemia‚ hypomagnesemia). Acute COPD exacerbation

Dr Cecil Burnett and other members of the cardiology department consulted on the patient. They felt that his hypoxemia and breathlessness were not secondary to his cardiac status. He had supraventricular cardiac arrhythmias‚ including atrial fibrillation in atrial flutter. The cardiology staff utilized intravenous medications that controlled the cardiac rate‚ adequately resolving these cardiac issues. I managed the patient’s ventilator and intensive care status along with my respiratory therapy

station. On her desk were three computer monitors. On the monitors were EKG’s of every patient in Telemetry A‚ B‚ and C. The technician went into detail about many different kinds of heart conditions. I learned what an EKG of Atrial Fibrillation and Ventricular Fibrillation looked like. She also printed me out a few examples of both. The technician showed professionalism when reporting on her patients. She did so by promptly alerting a nearby nurse when a patients heart rate was abnormal. This related

as sustained ventricular tachycardia. A period of three to five rapid beats is called a salvo‚ and six beats or more lasting less than 30 seconds is called nonsustained ventricular tachycardia. Rapid ventricular rhythms are more serious than rapid atrial rhythms because they make the heart extremely inefficient. They also tend to cause more severe symptoms‚ and have a much greater tendency to result in death. Although it is mostly known to be one of the life-threatening abnormal rhythms‚

Sudden cardiac death happens more these days. There are so many people alone in the United States who just stops breathing with no heart disease involved. So why did their heart stop? There are so many researchers out there trying to figure out the underlying cause of these people who this happen to. There can be other reason why a person’s heart can stop without having a cardiac disease. A person’s body may store minerals that control the arrhythmia of the heart to act a different way.

that administers an electric shock of preset voltage to the heart through the chest wall in an attempt to restore the normal rhythm of the heart during ventricular fibrillation. Defibrillation is a procedure used to treat life threatening conditions that affect the rhythm of the heart such as cardiac arrhythmia‚ ventricular fibrillation and pulseless ventricular tachycardia. The procedure involves the delivery of an electric shock to the heart which causes depolarisation of the heart muscles and
