What is the term for a beat that comes too early?
Bradycardia
What is the term for a heart rate that is too slow?
Tachycardia
What is the term for a heart rate that is too fast?
Supraventricular
What is the term for an ectopic beat originating above the AV groove?
Ventricular
What is the term for an ectopic beat originating below the AV groove?
Syncope, weakness, decompensation of CHF, reduced CO and blood flow, death
What are some common signs of cardiac arrhythmias?
False (some are physiologic)
True or false: All arrhythmias are pathologic
Auscultation, ECG
What are the 2 common ways we identify arrhythmias?
Normal P waves that trigger typical QRS-T, normal HR for species
What are the general characteristics of normal sinus rhythm?
None (normal sinus rhythm)
What is the abnormality in this dog ECG?
Image: None (normal sinus rhythm)
Sinus arrhythmiaWhat is the abnormality in this dog ECG?Cyclic variation of PP intervals, normal PQRST complexes, may vary with respiration, wandering pacemakerWhat are the typical characteristics of sinus arrhythmia?Different areas of SA node initiate the firing, leading to different morphology of P wavesWhat is occurring in wandering pacemakers?Dogs, horsesIn what animals is sinus arrhythmia normal?Sinus arrhythmia, wandering pacemakerWhat is the abnormality in this dog ECG?Sinus bradycardiaWhat is the term for having a slower than normal sinus rhythm?Normal Complexes, regular rhythm, slower than expectedWhat are the characteristics of sinus bradycardia?Sinus tachycardiaWhat is the term for sinus rhythm, but faster than expected for that species?Sinus bradycardiaWhat is the abnormality in this dog ECG?Sinus tachycardiaWhat is the abnormality in this dog ECG?TrueTrue or false: in most cases, sinus tachycardia is the physiologically normal response to a secondary problem, so we should treat the underlying issue, not the arrhythmiaSupraventricular premature depolarizationsWhat is the term for when regular rhythm is interrupted by a premature depolarization from the atria or AV junctional tissue?Normal QRS-T appearance but occurs before it should, possible change in P wave, usually non-compensatoryWhat are the characteristics of APCs?Supraventricular premature depolarizationWhat is the abnormality in this dog ECG?Supraventricular premature depolarizationWhat is the abnormality in this dog ECG?Supraventricular TachycardiaWhat is the abnormality in this dog ECG?Runs of more than 3 APCs, normal QRS appearance, usually regularly spacedWhat are the characteristics of supraventricular tachycardia?Sustained Supraventricular TachycardiaWhat is the abnormality in this dog ECG?Large R ventricle (R wave tall), Supraventricular tachycardiaWhat is the abnormality in this dog ECG?Atrial fibrillationWhat is the term for the chaotic, disjointed activation of the atria?False (cannot pump any blood)True or false: the atria are able to pump some blood during atrial fibrillationUsually rapid, irregularly irregular RR intervals, lack of organized P waves, F wavesWhat are the characteristics of atrial fibrillation?F wavesWhat is the term for the baseline undulations due to atrial fibrillation on the ECG?Atrial fibrillationWhat is the abnormality in this dog ECG?SVT is regular rhythm, normal QRS, Afib is irregular, varying heights of QRS, no P wavesHow can you differentiate atrial fibrillation from SVT?Atrial fibrillationWhat is the abnormality in this dog ECG?Atrial fibrillationWhat is the abnormality in this dog ECG?Atrial fibrillationWhat is the abnormality in this horse ECG?Usually wide and strange QRS, T wave large and opposite direction of QRS, no ST segment shelf, compensatoryWhat are the characteristics of premature ventricular depolarization?VPCWhat is the abnormality in this dog ECG?Ventricular Bigeminy (alternating sinus and VPC)What is the abnormality in this dog ECG?VPCWhich is usually compensatory: APC or VPC?APCWhich is usually noncompensatory: APC or VPC?Ventricular tachycardiaWhat is the term for a run of 3 or more VPCs in a row?Wide and strange QRS, large T wave, ST shelf goneWhat is the typical appearance of ventricular tachycardia?Differentiate mutliform from uniform, Normals for boxers vs dobermansWhy do we care where in the ventricle the VPC is coming from?Sustained ventricular tachycardiaWhat is the abnormality in this dog ECG?Lasts more than 30 secondsWhat are the criteria from sustained ventricular tachycardia?Accelerated idioventricular rhythmWhat is the term for a "normal" heart rate but with VPCs rather than sinus rhythm?Accelerated idioventricular rhythmWhat is the abnormality in this dog ECG?VPCsWhich are more likely to negatively impact cardiac function: VPCs or APCs?Ventricular fibrillationWhat rhythm occurs when there is chaotic, disorganized activation of the ventricles?Irregular undulations in the baseline, no discernible wavesWhat are the characteristics of ventricular fibrillation on the ECG?Drops to 0What happens to the CO in ventricular fibrillation?CourseWhich is it easier to shock a patient out of: course or fine ventricular fibrillation?TrueTrue or false: Ventricular fibrillation is one of the most common ECG reading just before cardiac arrest
