What does bradycardia on a ECG trace look like?
Longer distances between QRS spike
What does the p indicate in an ECG trace?
PQRST
Atrial stimulation
What does the QRS indicate in the ECG trace?
PQRST
ventricular stimulation
What does the T wave indicate in the ECG trace?
PQRST
Diastole
What is purkyne tissue?
Super conductive tissue running down the interventricular septum that allows the wave of excitation to pass down to the bottom of the ventricals and cause a contraction starting from the base.
What is tachycardia?
A fast heart rate
What is atrial fibrillation and how would it look on an ECG trace?
When the atrium beats faster than the ventricle
lots of P waves but not clear as no distinction from T
What is an ectopic heart beat?
An early heart beat
What is the name of the valves going from atrium to ventricle?
Atro-ventricular
What is the name of the valves going from ventricle to the arteries? `
