Someone who has BORDERLINE blood pressure and is at risk of high blood pressure is said to have _____________________
A disease characterized by thickening, hardening, and loss of elasticity of the arterial walls--it can raise blood pressure if not treated
An organ OUTSIDE of the cardiovascular system that is damaged by long-term high blood pressure
A common food seasoning that is known to raise blood pressure

P wave and QRS wave
During what waves on an EKG is the electrical current?
What is depolarization in the heart?
during T wave
When is repolarization in the heart?
Premature ventricular contractions (PVC's)
Most common cause of irregular heart rhythms. Feels like a skipped heart beat. QRS are wide and bizzare shapes, often missing a P wave, T wave is large.
Pulse rate more thatn 100 pbm and 3 irregular heartbeats in a row. No P waves.
When the ST line is abnormally high above the isoelectric line (baseline). Often indicates a blood clot.
Small device to control abnormal heart rhythms. Used to treat arrhythmia.
When the heart beats too fast, slow, or irregular.
