a portable version of an EKG that is worn under the close by the patient for 24 to 48 hour.
on a Holter monitor chest electrodes are connected to the monitor and cardiac TV is continually monitored when?
while the patient goes about his usual daily activities.
the recording is scanned by an electro cardio scanner and?
a hard copy of the ECG is produced for review by the physician
besides ECG abnormalities what Cao Holter monitor evaluate?
the effectiveness of any anti-arrhythmic drugs and to associate the occurrence of chest pain with stress or physical activity
what does a looping Holter monitor do?
it loops the activity so when the patient pushes the button to record it can record a few seconds before they push the button to a few seconds after
what does a non-looping Holter monitor do?
it only begins to record when the patient pushes the button.
the stimulus is then sent to the bundle of HIS and the left and right bundle branches to the Purkinje fibers. This produces the ventricle depolarization and contractions
how much voltage does 10 vertical small blocks or two vertical large blocks represent EKG paper?
what is the electrode?
an object place in the skin to to conduct electrical current from the body to a monitoring or measured device
what happens when the impulse of the heart moves towards the positive electrode
an upward deflection is made on the ECG paper
what would cause a downward deflection made on the ECG paper?
the impulse of the heart moving towards the negative electrode
what are the rates of; bradycardia, tachycardia, flutter, fib, and normal heartbeats
<60 bradycardia, >100 tachycardia, >200 flutter, fib is too fast account, 60 to 100 normal heart rate
atrial rate >60, ventricular rate <40, PR intervals cannot be determined, QRS complex will be widened
third-degree AV block
what does the axis of the ECG measure
the direction of all electricity to the heart during contraction
normally what corner does the electrical impulse of the heart begin at
upper right-hand corner at the SA node in the right atrium
what direction does the electrical impulse travel in the heart
down and across the heart to the left
