Sinus rhythm with first degree av block then ventricular tachycardia

Sinus rhythm with first degree av block then ventricular tachycardia-Junctional ectopic tachycardia(JET) is a rare childhood arrhythmia originating from the area adjacent to the atrioventricular(AV) node It often occurs after surgical procedures like repair of Tetralogy of Fallot, atrioventricular septal defect and ventricular septal defect, which are all performed in that area While AV block (AVB) can occur after JET, it is very rare for late JET occurring after early postoperative AVB to be followed by normal sinus rhythmThis is a good ECG for demonstrating sinus brady and firstdegree AV block It shows the sinus node in the process of slowing down For your more advanced students, there is left axis deviation due to left anterior fascicular block (left anterior hemiblock) The ST segments are flat, suggesting coronary artery disease The fourth (bottom) channel is a good rhythm strip

If it is ventricular tachycardia, the rhythm will likely be unaffected, and procainamide, amiodarone, or sotalol should be administered17 If the patient remains unstable, cardioversion is/03/21Onset of ventricular tachycardia most VTs appear after a premature ventricular complex AV dissociation in patients with an underlying sinus rhythm, the atria may be stimulated by sinus node So atrial and ventricular rhythms are independent, presenting dissociation between P waves and QRS complexes This one of the most important diagnostic criteria for ventricular tachycardia 4 More information Ventricular tachycardiaNonconducted PACs or Sinus arrhythmia;

In firstdegree AV block (Figure 819 and Box 85), the sinus impulse is normally conducted to the AV node, where it's delayed longer than usual before being conducted to the ventricles This delay in the AV node results in a prolonged PR interval (>/03/21Premature ventricular complexes (PVCs), also known as premature ventricular contractions, ventricular premature beats (VPBs) or ventricular extrasystoles, are ectopic impulses originating from an area distal to the HisPurkinje system Premature ventricular complexes are the most common arrhythmia observed in patients without structural heartSeconddegree AV block Mobitz type II Mobitz type 2 block implies that some atrial impulses are blocked sporadically The PR interval is constant (although it may be prolonged) Mobitz type 2 is more serious, because it is usually chronic and tends to progress to thirddegree AV block Moreover, cardiac output may be reduced if many impulses are blocked Approximately % of patients have a block located in the bundle of His, and 80% have a block

Firstdegree atrioventricular block (AV block) is a disease of the electrical conduction system of the heart in which electrical impulses conduct from the cardiac atria to the ventricles through the atrioventricular node (AV node) more slowly than normal First degree AV block does not generally cause any symptoms, but may progress to more severe forms of heart block such as secondINTRODUCTION Delayed higherdegree atrioventricular (AV) block can develop after slow pathway ablation for AV nodal reentrant tachycardia with a preexisting firstdegree AV block Retrograde fast pathway ablation is considered as an alternative approach for patients with a markedly prolonged PR interval and no demonstrable anterograde fast pathway function atDemand Ventricular Pacing Biventricular paced with a run of Ventricular Tach Bigeminal PVCs;

Atrial tachycardia and other ectopic atrial rhythms occur when a site outside of the sinus node, but within the atria, creates action potentials faster than the sinus node This ectopic focusA "shortRP" tachycardia is often characterized by RP<PR, which translates to a short VA and long AV time It can be atrial tachycardia with a 1st degree AV block (delay in the AV node during tachycardia), sinus tachycardia with a 1st degree AV block, typical slowfast AVNRT, and orthodromic AVRT/03/21Ventricular Escape Rhythm or Idioventricular Rhythm Ventricular escape rhythm or idioventricular rhythm occurs in the absence of supraventricular stimuli or with bradycardias with heart rate below 40 bpm (sick sinus syndrome or complete AV block distal to the bundle of His) 3Ventricular escape rhythm is observed on the electrocardiogram as a slow, regular rhythm

Ventriculophasic sinus arrhythmia is present when alterations in the sinus rate are due to atrioventricular (AV) block The PP intervals enclosing a QRS complex are shorter than PP intervals not enclosing a QRS complex A change in sinus rate can be gradual or abrupt and can occur with change in body position and exerciseAtrial flutter Rate >250bpmFirst degree block is rarely diagnosed (although likely occurs relatively frequently), and rarely is a problem because the manifestation is simply a longer delay between the normal coupling of atrial and ventricular activities Second degree AV block is relatively common when anesthetic and preanesthetic drugs that enhance vagal tone are used (eg, opioids, alpha 2 adrenergic agonists, low doses of anticholinergics) Two subclasses of second degree AV block

According to MacFarlane et al (Comprehensive Electrocardiology, Springer, 10) trifascicular block is defined as presence of a bifascicular block with simultaneous first or seconddegree AV block However, the term trifascicular block should not be used as it causes more confusion and enlightenment It is advised that each defect be stated separatelyCommon nonpathologic variations of normal sinus rhythm are seconddegree atrioventricular (AV) block, sinus block and sinus arrhythmia Seconddegree AV block occurs with high resting vagal tone that slows conduction of impulses from the SAN to the AVNSupraventricular tachycardia (SVT) SIGNS / SYMPTOMS INVESTIGATIONS SIGNS / SYMPTOMS In patients with profound firstdegree AV block and very long PR intervals, the P wave may encroach so closely on the QRS complexes that they appear to be retrograde P waves, suggesting SVT Retrograde P waves in SVT are frequently inverted in the inferior leads versus upright in sinus rhythm with first
