16
Q

What does the AV node delay the signal for?

A

The ventricles to fill then stimulates through purkinje network of fibers. (Simultaneous contraction of (B) ventricles

17
Q

Electrical current recorded at ECG.

What does the P wave represent?

A

Atrial contraction

18
Q

What does the QRS represent?

A

Ventricular contraction

19
Q

What is the Third wave?

A

Recovery wave

20
Q

What do Arrhythmias show I the ECG?

A

Problems such as

  • Infarction
  • Systemic electrolyte imbalances
21
Q

Treatment of Cardiac Dysrhytmias

A

Cause needs to be determined and treated

Antidysrhythmic drugs are effective in many cases

22
Q

Treatment of Ca Dys

What requires a pacemaker?

A

SA nodal problems or total heart block

23
Q

Treatment of Ca Dysr

Why is a Defibrillator implanted?

A

Conversation of ventricular fibrillation (ineffective electrical activity at the moment)
