Q

Describe Long QT Syndrome

A

may be congenital or acquired and causes recurrent syncope, a QT interval usually 0.5 to 0.7 seconds long, ventricular arrhythmias, and sudden death

Q

what is the preferred pharmacologic agent for acute V tach

A

lidocaine, procainamide, and amiodarone

empiric magnesium may help

16
Q

When do you use an implantable debrillator to treat Ventricular arrhythmias?

A
  1. chronic recurrent sustained V tach without a reversible cause
  2. congenital long QT syndrome
  3. Brugada’s syndrome
17
Q

What is the treatment for Torsades de Pointes

A

BB, magnesium, and temporary atrial or ventricular pacing

18
Q

When is Sick Sinus Syndrome Reversible?

A

caused by digitalis, quinidine, B-Blockers, or aerosols

19
Q

a wastebasket of arrhythmias caused by SA Node dysfunction associated with unresponsive supraventricular (atrial and Junctional) automaticity foci, which are also dysfunctional and cant employ their normal escape mechanism to assume pacing responsibility

A

SSS

20
Q

patients with SSS may develop intermittent episodes of SVT (sometimes even Aflutter or Afib) mingled with the Sinus Bradycardia what is this?

A

Bradycardia- Tachycardia Syndrome

21
Q

describe the clinical features of SSS and AV Block

A

SSS = syncope, dizziness, confusion, heart failure, or angina
AV block = weakness, fatique, light headed ness, and syncope

22
Q

What is the treatment for SSS?

What is the treatment for AV Block?

A

SSS = permanent pacemaking if the pt is symptomatic

AV block = cardiac pacing
