|
Temporary pacing
|
|
Treatment focuses on finding the primary cause. If it's high catecholamine levels, a beta-adrenergic blocker may slow the heart rate. After myocardial infarction, it may precede heart failure or cardiogenic shock.
|
Sinus tachycardia
|
|
Atrial rhythm: regular
Ventricular rhythm: regular Atrial rate: 100 to 160 bpm P wave: As the rate reaches about 150 bpm, the P wave merges with the preceding T wave and may be difficult to identify. Examine the descending slope of the preceding T wave closely for notches, indicating the presence of the P wave. Other: gradual onset and cessation |
Sinus tachycardia
|
|
If the pt is asymptomatic, treatment isn't necessary. If he has signs and symptoms, treatment aims to identify and correct the underlying cause. The heart rate may be increased with such drugs as atropine and isoproterenol (Isuprel). A temporary or permanent pacemaker may be inserted if the bradycardia persists.
? |
Sinus bradycardia
|
|
Atrial rate: less than 60 bpm
Vent. rate: less than 60 bpm |
Sinus bradycardia
|
|
This rhythm often degenerates into ventricular fibrillation and cardiovascular collapse, requiring immediate cardiopulmonary resuscitation and defibrillation. If the pt is symptomatic, prepare for immediate cardioversion, followed by antiarrhythmic therapy. Lidocaine (Xylocaine) is usually administered immediately. If it proves ineffective, procainamide (Pronestyl) or bretylium (Bretylol) is used?
|
Ventricular tachycardia
|
|
Atrial rhythm: p waves probably not visible or independent P waves possibly discernible with slower ventricular rates
Ventricular rhythm: usually regular but may be slightly irregular Atrial rate: can't be determined Ventricular rate: usually 100 to 200 bpm P wave: usually absent; possibly obscured by the QRS complex; retrograde P waves possible presence PR interval: not measurable QRS complex: duration greater than 0.12 second; bizarre appearance, usually with increased amplitude T wave: opposite the terminal forces of the QRS complex QT interval: not measurable |
Ventricular tachycardia
|
|
Perform cardiopulmonary resuscitation until the pt can receive defibrillation. Administer epinephrine if initial defibrillation series is unsuccessful. Other drugs that may be used include lidocaine (Xylocaine), bretylium (Bretylol), and procainamide (Pronestyl). Magnesium sulfate may be used for torsades de pointes or refractory ventricular fibrillation?
|

|
|

Ventricular rhythm: irregular Atrial rate: can't be determined Ventricular rate: can't be determined P wave: indiscernible PR interval: not measurable QRS complex: replaced with fibrillatory waves; duration not discernable T wave: can't be determined QT interval: not measurable |
Ventricular fibrillation
|
|
Treatment aims to identify and manage the primary problem that triggered this safety mechanism. Atropine or dopamine (Intropin) may be given to increase the atrial rate. A pacemaker may also be inserted to increase the heart rate and thereby improve cardiac output?
|
Idioventricular rhythm
|
|
Atrial rhythm: can't be determined
Ventricular rhythm: usually regular, except with isolated escape beats Atrial rate: unable to be determined Ventricular rate: less than 40bpm P wave: absent PR interval: usually not measurable QRS complex: duration greater than 0.12 second; complex is wide and has a bizarre configuration T wave: directed opposite terminal forces of QRS complex QT interval usually greater than 0.44 second |
Idioventricular rhythm
|
|
PR interval: greater than 0.20 second and constant
|
First degree AV block
|
|
If the pt is asymptomatic; no intervention is required other than monitoring the electrocardiogram frequently to see if a more serious form develops. If the pt is symptomatic; the doctor may order atropine to increase the rate and to stop the decremental conduction through the AV node. Occasionally, the doctor may insert a temporary pacemaker to maintain an effective cardiac output.
|
Second-degree atrioventricular block, type 1
|
|
Ventricular rhythm: irregular
Atrial rate: determined by the underlying rhythm Ventricular rate: slower than the atrial rate PR interval: progressively prolonged with each beat until a P wave appears without a QRS complex QRS complex: periodically absent Other: usually distiguished by a pattern of group beating, referred to as the footprints of Wenckebach? |
Second-degree atrioventricular block, type 1
|
|
If the pt is hypotensive, treatment aims at increasing his heart rate to improve cardiac output. Because the conduction block occurs in the His-Purkinje system, drugs that act directly on the myocardium usually prove more effective than those that increase the atrial rate. As a result, dopamine (Intropin) instead of atropine may be ordered to increase the ventricular rate.
If the pt has an anterior wall MI, the doctor will immediately insert a temporary pacemaker to prevent ventricular asystole. For long-term managment, the pt usually needs a permanent pacemaker. |
Second-degree atrioventricular block, type 2
|
|
Ventricular rhythm: regular or irregular
Ventricular rate: may be within normal limits but less than the atrial rate QRS complex: usually greater than 0.16 second because of the presence of a preexisting bundle-brance heart block |
Second-degree atrioventricular block, type 2
|
|
If cardiac output isn't adequate or the pt's condition is deteriorating, the doctor will order therapy to improve the ventricular rhythm. Initially, atropine may be ordered to increase the ventricular rate and improve cardiac output until a pacemaker is available?
|
3rd degree AV block
|
|
Atrial rhythm: usually regular
Ventricular rhythm: usually regular Atrial rate: usually within normal limits Ventricular rate: slow PR interval: not measurable because the atria and ventricles beat independently of each other QRS complex: determined by the site of the escape rhythm (With a junctional escape rhythm, the duration and configuration are normal; with an idioventricular escape rhythm, the duration is greater than 0.12 second and the complex is distorted) QT interval: may or may not be within normal limits |
