Ventricular tachycardia

VENTRICULAR TACHYCARDIA Description Ventricular tachycardia is a type of Ventricular arrhythmia, or a rapid heart beat that arises from improper electrical activity of the heart presenting as a rapid heart rhythm. It starts in the bottom chambers of the heart, called the ventricles. This is a potentially life-threatening arrhythmia because it can cause low blood pressure and may lead to ventricular fibrillation, asystole, and sudden death. Causes Arrhythmias are due to problems with the electrical conduction system of the heart. Symptoms 1. Run of three or more consecutive ventricular beats at a rate >120 beats/min. 2. If the rate of consecutive ventricular beats is >100/min, it is called accelerated idioventricular rhythm which is a benign condition, usually occurring following the thrombolytic therapy. Diagnosis…

an AMI. This pattern is defined as a ventricular rhythm characterized by a wide QRS complex with a regular escape rate faster than the atrial rate, but less than 100 bpm. AV dissociation is frequent. Slow, nonconducted P waves are seen; these are unrelated to the fast, wide QRS rhythm. Most episodes are short and terminate spontaneously. They occur with equal frequency in anterior and inferior infarctions (Ashok et al. 2011). This arrhythmia results from either (1) Failure or structural damage…

Physiological Effects of Monomorphic Ventricular Tachycardia Ventricular tachycardia (VT) is a disease of the heart, in which the heart’s normal rhythmic contraction is altered, changing the heart function (Ideker &Walcott, 1993). It is characterized by having a heartbeat that is too fast, although the disease itself is far more complex (Ideker & Walcott, 1993). Ventricular tachycardia often leads to ventricular fibrillation (VF), and together, they are among the most life threatening cardiac…

A growing number of non-cardiac drugs have been found to delay cardiac repolarization, causing QT interval prolongation and predisposing patients to an increased risk of potentially fatal ventricular arrhythmias, known as torsade de pointes (TdP) (Letsas et al, 2007; Yap and Camm 2003; Sanguinetti and Tristani-Firouzi). These drugs include the second-generation, non-sedating antihistamines astemizole and terfenadine, withdrawn from the market in Europe and the United States (in 1997 and 1999,…

Syncope "Syncope is defined as an abrupt, transient loss of consciousness and postural tone with spontaneous recovery, most often caused by loss of cerebral oxygenation and perfusion referred to as cerebral ischemia. Syncope is also referred to as transient loss of consciousness (Grimes, 2014)." Syncope is considered the most common medical emergency in dental offices around the world (Grimes, 2014). It can most likely occur when blood pressure is too low (hypotension) and the heart is not…

VASOVAGAL SYNCOPE 3 Vasovagal Syncope It starts with a feeling of whirling sensation, followed by blurred vision, and a muffled sense of hearing, until one unknowingly wakes up on the floor, wondering what had happened. This type of syncope is the classic movie scene when someone receives shocking news and passes out (Team, 2015). As scary as it is, this type of fainting is quite common in the United States. Vasovagal syncope is a result of a sudden drop in heart rate and blood…

caused from a premature atrial complex. I remember this as “aberrant, randomly present”. There are three hearts blocks that you must differentiate through their similarities. A first-degree heart block, has a p-wave that measure longer through each complex. I remember this as “long, longer, drop”. The second-degree heart block, has two p-waves per complex with equal measurements, it’s the “twin block”. The third-degree heart block is a fatal rhythm it will have non-correlating and multiple…

single-pass is only used on one chamber (Lerner and Lerner, 2014). There is two different normalities bradycardia and tachycardia. Bradycardia is when the heartbeat is very slow and tachycardia is when the heart is overactive and beats very fast (Lerner and Lerner, 2014). To continue in the article “Cardiac Pacemakers, Inc.; Patent Issued for Method and Apparatus for Cardiac Arrhythmia Classification Using Sample Entropy” by Dan Li it says the heart is the main system in the body, which helps…

Profile Assignment Throughout our family we have always had heart disease in our genes, on both my mom’s side and my dad’s. I was lucky enough not to get it, but my brother wasn’t. My brother, Dante was born with no heartbeat the doctors took him out right away and revived him. They did tests and found out he had wolff parkinson white and long q t syndrome. A heart disease that mostly starts happening when he does physical movements. His heart will start to be very fast, up to over 400 beats per…

disturbances in the brain. Symptoms of this disorder may include loss of consciousness, convulsions, spasms, and sensory confusion. Attacks are frequently preceded by strange behavior and feelings of uneasiness or discomfort. Similarly, meningitis can develop; an infection that causes inflammation of the membranes that surround the brain. Symptoms may include a general feeling of ill health, nausea, abdominal pain, along with stiffness in the back and neck. Others conditions involved with…
