Age — A WCT in a patient over the age of 35 years is likely to be VT positive predictive value 85 percent in one series [11]. It is also important to establish whether a cardiac arrhythmia has occurred in the past and, if so, whether the patient is aware of the etiology.

Unstable — This term refers to a patient with evidence of hemodynamic compromise, but who remains awake with a discernible pulse.

Three types of idiopathic VT arising in or close to the outflow tract of the right ventricle see text. Patients are auriculventricular to carry identification cards providing information about such devices, which can facilitate device interrogation.

Puede existir y no ser obvia en ECG. The QRS complex will be smaller when the VT has its origin in or close to the interventricular septum. Also the presence of AV conduction disturbances during sinus rhythm make it very unlikely that a broad QRS tachycardia in that patient has a supraventricular origin and, as already shown in fig 11, a QRS width during tachycardia more narrow that during sinus rhythm points to a VT. That area is difficult to reach by retrograde left ventricular catheterisation and when catheter ablation is considered an atrial transseptal catheterisation should be favoured.

The first criterion is the presence of a positive and dominant R wave in lead aVR, and the second is based on the vi: Some patients with a WCT have few or no symptoms palpitations, lightheadedness, diaphoresiswhile others have severe manifestations including chest pain or angina, syncope, shock, seizures, and cardiac arrest [6].

The arrhythmia is often responsive to treatment with b blockers, sotalol9 or calcium channel blockers and can also be amenable to transcatheter ablation. On the right a VT arising on the right side of the interventricular septum results in more simultaneous activation of the right and left ventricle than during sinus rhythm and therefore a smaller QRS complex. Catheter ablation fig 8 12 offers curative therapy and should be considered early in the management of symptomatic patients. Note the baseline QT prolongation, with abrupt lengthening of the QT interval after the pause, followed by the onset of polymorphic ventricular tachycardia, which suddenly terminates.

This can be found either in VT originating in the left posterior wall or during tachycardias using a left posterior accessory AV pathway for AV conduction fig In fact, there is an important rule in LBBB shaped VT with left axis deviation that cardiac disease should be suspected and that idiopathic right ventricular VT is extremely unlikely.

On the left sinus disociacioh is present with a very wide QRS because auriciloventricular anterolateral myocardial infarction and pronounced delay in left ventricular activation. Stable — This refers to a patient showing no evidence of hemodynamic compromise despite a sustained rapid heart rate. Nondiagnostic J point dosociacion in precordial leads V1 and V2. SVT not associated with structural cardiac disease or drug presence, for example, would be expected to show rapid initial forces and delayed mid-terminal forces.

However, these forms may just represent different spectra of the same arrhythmia. When the rate is approximately beats per minute, atrial flutter with aberrant conduction should be considered, although this diagnosis should not be accepted without other supporting evidence.

Symptoms — Symptoms are not useful in determining the diagnosis, but they are important as an indicator of the severity of hemodynamic compromise. It is important to recognise this pattern because this site of origin of the VT cannot be treated with catheter ablation in contrast to the tachycardias depicted in panel A and B C, Eje QRS: Auriculogentricular any of criteria 1 to 3 was present, VT was diagnosed; when absent, the next criterion was analyzed. If they are P waves, they occur in 1: Never make the mistake of rejecting VT because the broad QRS tachycardia is haemodynamically well tolerated.

Aurculoventricular purpose of this study was to further simplify the algorithm by omitting the complicated morphologic criteria and restricting the analysis to lead aVR. In this setting, emergent synchronized cardioversion is the treatment of choice regardless of the mechanism of the arrhythmia.

Of course other factors also play a role in the QRS width during VT, such as scar tissue after myocardial infarctionventricular hypertrophy, and muscular disarray as in hypertrophic cardiomyopathy. Muesca en descenso inicial del QRS neg.

ILVT is thought to have a re-entrant basis or derives from triggered activity secondary to delayed afterdepolarisations. The QRST complexes of the sinus-conducted beats are normal. AV dissociation may be present but not obvious on the ECG. Left panel VT; right panel same patient during sinus rhythm.

The following findings are helpful in establishing the presence of AV dissociation. An atrial rate that is faster than the ventricular rate is seen with some SVTs, such as atrial flutter or an atrial tachycardia with 2: TV Eje izquierdo frontal V6 Marriott6 described that in RBBB shaped tachycardia, presence of a qR or R complex in lead V1 strongly argued for a ventricular origin of the tachycardia, while a three phasic RSR pattern suggested a supraventricular origin.

Often, no treatment is required, and the rhythm disturbance is self-limited. IM anteroseptal Miocardiopatia dilatada idiop.
