|---|---|---|---|---|---|
| What is the first tool used in the evaluation of a patient with palpitations? | show 🗑
|
||||
| What are the pros + limitations of using an ECG? | show 🗑
|
||||
| show | Holter or Ambulatory monitoring; can provide beat by beat analysis of the rhythm; most helpful if symptoms occur at least once every 24 hours
🗑
|
||||
| show | Useful if symptoms less frequent (once ever 2-6 weeks); patient wears recorder and activates it (must be conscious) when they get symptoms; information transmitted via telephone to central station
🗑
|
||||
| What's an alternative to a loop recorder if the patient is frail or if the symptom includes frank syncope? | show 🗑
|
||||
| When is signal averaged ecg useful? What types of ECG abnormalities affect the reliability of the measurement? | show 🗑
|
||||
| What is heart rate variability (HRV) technique useful for? | show 🗑
|
||||
| show | increased mortality; inspect using Heart rate variability (HRV)
🗑
|
||||
| show | Looks at microvolt changes in T-wave amplitude; studies suggest that negative predictive power of test could be used to identify low risk population
🗑
|
||||
| show | The electrophysiology study (EP); invasive
🗑
|

|
||||
| Vaughn-Williams Class IA drug actions | show 🗑
|
||||
| Vaughn-Williams Class IB drug actions | show 🗑
|
||||
| show | no change in ERP and A duration; decreased slope phase 0 & 4
🗑
|
||||
| Vaughn-Williams Class II drug actions | show 🗑
|
||||
| show | Increase AP duration and ERP; increased PR interval; increased QRS duration; increased QT duration
🗑
|
||||
| show | Increased ERP of AV node, blocks slow Ca++ channel current
🗑

| show | Amidarone: pulmonary toxicity, bradycardia, GI symptoms, thyroid and liver abnormalities. Sotalol: All class II side effects + proarrhythmia. Dofetilidie: torsade de Pointes
🗑
|
||||
| show | Hypotension, bradycardia, worsening AV lock, Liver function abnormalities
🗑
|
||||
| show | VW Class Ia, Ic, and III drugs; II and IV if AV ivolved; Ib do not appear useful
🗑
|

🗑
|
||||
| What two drugs have been shown to been effective in reducing the risk of stroke in patients with afib? | show 🗑
|
||||
| CHADS2 risk factors | show 🗑
|
||||
| How should you treat a patient with afib that is symptomatic and unstable? Minimally or asymptomatic? | show 🗑
|
||||
| show | recurrent paroxysmal atrial fibrillation and recurrent persistent atrial fibrillation
🗑
|
||||
| Antiarrhythmic drug therapy is needed for A.fib. patients if: | show 🗑
|
||||
| show | Anticoagulation and rate control
🗑
|
||||
| show | Advantages: inexpensive, widely available. Disadvantages: poorly controls rate during activity, digitalis toxicity serious problem
🗑
|
||||

| What are some of the advantages + disadvantages of using amiodarone for rate control during a.fib.? | show 🗑
|
||||
| What are some of the advantages + disadvantages of using AV node ablation for rate control during a.fib.? | show 🗑
|
||||

|
||||
| How do you treat VT in patients with CAD? | show 🗑
|
||||
| How do you treat patients with AV node reentrant tachycardia and SVT associated with WPW? | show 🗑
|
||||
| show | Supraventricular tachycardias and ventricular tachycardias
🗑
|
||||
| show | Class I indications: symptomatic bradycardia; asystole > 3.0 seconds; symptomatic complete or high grade AV block; asymptomatic complete heart block with an escape rate <40 bpms

🗑
|
||||
| show | Bi-ventricular pacing; up to 75% show improvement with reduction in LV size and increases in LV ejection fraction
🗑
