5 Bradyarrhythmias Sinus Node AV Conduction Medications Vagus Nerve Catechols AV Node His bundle or Purkinje system Discontinue Med or Implant Pacemaker
6 Tachyarrhythmias Atrial Conduction System Ventricular Focal Reentry Focal Reentry Focal Reentry Medication or Catheter Ablation
7 Palpitations Fast heart rate Slow heart rate Strong heart beat Extra beat(s) Skipped beat(s) Irregular heart beat Fluttering Butterflies Flip Flop Pounding Racing Start & Stop Once Seconds Minutes Hours Days Daily Weekly Monthly Yearly
8 Arrhythmia Mimics Symptoms History GI symptoms Reflux, eso spasm Muscle symptoms Pectoral, intercostal Panic attack Anxiety disorder Tripped and fell Seizures Car accident Drowning Heart attack
9 Ways To Record Arrhythmias ECG Non-Loop Monitor Holter Looping Monitor Smart Phone App Implantable Monitor
10 Slow Heart Rhythms
11 Sinus Node Setting the Pace!
12 Example #1 Sinus Node Dysfunction 3:00pm - HR 39 bpm Example #2 3:00am second pause
13 Tachy Brady Syndrome 5.5 second pause Atrial Fibrillation Sinus Node Resumes Firing after Being Suppressed
14 Chronotropic Incompetence Slow, Unchanging Heart Rate Normal Heart Rate Distribution
15 AV Conduction Delivering the Message!
16 Mobitz I (Wenckebach) Block occurring in AV node Typically narrow QRS (Purkinje tree is OK) Grouped beating Prolonging PR interval until blocked beat PR after pause shorter than PR before
17 Mobitz II Block occurring in His-Purkinje System Usually wide QRS (Purkinje tree missing branches) Often not in a pattern PR intervals constant all or none
18 Mobitz II Can progress to asystole at any time! (few minutes later)
19 Side-by-Side Comparison - ECG From Med-on-Line, David C. Chung, MD
20 Third Degree Heart Block aka Complete Heart Block No signals get through from A to V Substitute, slower pacemaker spot takes over AV dissociation Rate of escape rhythm depends on location
21 Pacemaker - Works for All Types of Bradycardia Pacemaker Right Atrium Right Ventricle
22 Fast Heart Rhythms
23 From the Atria Atrial Fibrillation Atrial Flutter Atrial Tachycardia
24 From A-V Connections AV Node Reentry (AVNRT) AtrioVentricular Reciprocating Tachycardia using Accessory Pathway (AVRT) Fascicular Tachycardia
25 From the Ventricles Focal Ventricular Tachycardia (and PVCs) Scar-based Ventricular Tachycardia
26 Premature Atrial Beat (PAC)
27 Premature Ventricular Beats (PVCs)
28 Extra Beats or Skipped Beats?
29 Supraventricular Tachycardia (SVT)
30 Atrial Flutter
31 Atrial Fibrillation Slow V.rate
32 Atrial Fibrillation Fast V.rate
33 Sustained Automatic VT
34 Taking an Arrhythmia History When did symptoms start happening? How long do symptoms last? How often do episodes occur? Do they start and stop suddenly? Is the heartbeat regular or irregular? Any other symptoms at same time? Lightheadedness or fainting? Pattern? Time? Exercise/rest? Have you taken your pulse during a spell?
35 What Triggers Fast Rhythms? Stress Fright Fatigue Dehydration Illness After exercise At rest (in bed) Thyroid or endocrine problems Menstrual cycle Caffeine Alcohol Stimulants Sudafed Albuterol (Ventolin) Caffeine pills Diet medications Heart conditions Electrical abnormalities since birth
36 Making the Diagnosis ECG in office or emergency room 24 hour Holter monitor 30 day event monitor Smart phone application Implantable loop monitor Exercise stress test Refer to an electrophysiologist
37 ECG in ER
38 30-day Event Monitor
39 30-day Event Monitor
40 AliveCor Application
41 Implantable Loop Monitor
42 Treatment Options Depends on diagnosis and severity No treatment needed Change in behavior (cut down caffeine, etc.) PRN Medication as needed for symptoms Daily Medication(s) B-blocker, AV node blockers, Antiarrhythmic meds Anticoagulant for a.fib, a.flutter Catheter ablation procedure Pacemaker implantation for bradyarrhythmias ICD implantation for life-threatening VT/VF
