MA: EKG Exam define tachycardia -       fast, rapid heartbeat bradycardia -       slow heartbeat arrhythmia -       improper beating of the hear (irregular/too fast/ too slow) cardiac ischemia -       lack of blood flow and oxygen to the heart muscle ventricular fibrillatin -       life-threatening heart rhythm that results in a rapid, inadequate heartbeat premature contractions -       extra, abnormal heartbeats that begin in the ventricles holter monitor -       portable device that records the rhythm of the heart continuously myocarditis -       inflammation in the muscle of the heart dyshythmia -       abnormality in physiological rhythm, in the activity of the brain/heart athersclerosis -       diseases of the arteries by the deposition of plaques of fatty material on their inner walls myocardial infarction -       another term for heart attack sinus rhythm -       any cardiac rhythm where depolarization of the cardiac muscle begins at the SA node. what part from the ECG waveform represents ventricular repolarization? -       T wave what part from the ECG waveform represents atrial depolarization? -       P wave this part from the waveform represents the time it takes for the cardiac impulse to travel from the atria to the ventricles -       PR interval what part from the ECG waveform represents ventricular depolarization -       QRS complex what part from the ECG waveform represents the end of ventricular depolarization and the beginning of ventricular repolarization -       ST segment what speed does the paper move while recording a normal electrolcardiogram -       25 mm/s why would the paper be advanced to a faster speed? -       if the patient has tachycardia, the paper would need to be in a faster speed what is a Holter Monitor? -       a portable ambulatory monitoring system, that monitors over a 24 hour period what is the purpose for a holter monitor? -       to get a view of the heart beat over an extended time frame what is the stress test? -       monitors the heart beat with an increasing work load. what are artifacts? -       appearances on the EKG tracing that are not natural and interfere with the normal appearence what is another term for a muscle artifact? -       Somatic interference what are wandering baselines caused by? -       loose electrodes, dried out electrodes, excess body oil, lotions and somatic movement. what does AC interference stand for? -       alternating current what causes AC interference/60 cycle interference? -       other electrical equipment in use near the electrocardiograph what does teletransmission do? -       it is an EKG that is recorded in digital format and can be transmitted electronically to an EKG data interpretation site. define Interpretive Electrocardiograph -       helps provide immediate information on the heart's activity, which leads to earlier diagnosis and treatment.
