A

2 normal beats and PVC

38
Q

A

6 or more

40
Q

Ventricular Couplet

A

2 V Tach (unifocal PVCS)

41
Q

What dictates HR and rhythm for Premature Atrial Contraction

A

varies depending on underlying rhythm

42
Q

Characteristics of PAC

A

PAC P wave will always look weird
SA node sends a premature signal
Irregularly sent

43
Q

How do you find the rhythm and heart rate of a ventricular Bigeminy?

A

You can’t because there not at least 3 rhythms in a row

44
Q

How do you name a ventriuclar Bigeminy?

A

You just call it a ventricular Bigeminy since you can’t find the rhythm

45
Q

How would you name a rhythm with two beats before a run of V Tach

A

2 beats before a run of # V Tach

46

51
Q

What is the cause of AV (atrioventricular blocks)

A

AV Nodal disease

52
Q

Longer, longer, longer, drop makes the rhythm

A

Wenckebach (Second Degree AV Block Type 1/ Mobitz 1)

53
Q

2 causes of SVT
