arrhythmia

 [ah-rith´me-ah]
variation from the normal rhythm, especially of the heartbeat; see also dysrhythmia. adj., adj arrhyth´mic.
sinus arrhythmia the physiologic cyclic variation in heart rate, originating in the sinoatrial node and related to vagal impulses to the node; it occurs commonly in children (juvenile arrhythmia) and in the aged.

(ă-ridh'mē-ă), Avoid the misspelling arhythmia.
Loss or abnormality of rhythm; denoting especially an irregularity of the heartbeat. See also entries under rhythm Compare: dysrhythmia.

arrhythmia

(ə-rĭth′mē-ə)
n.
1. An irregularity in the force or rhythm of the heartbeat: a fatal arrhythmia.
2. A condition characterized by such irregularities: treatments for cardiac arrhythmia.

arrhythmia

Cardiac pacing Any rhythm in the heart that falls outside the norm with respect to rate, regularity, and propagation sequence of depolarization wave. See Atrial arrhythmia, Cardiac arrhythmia, Proarrhythmia, Reentrant arrhythmia, Ventricular arrhythmia Cardiology Any variation in the normal rate or periodicity of heart beats.

arrhythmia

Any abnormality in the regularity of the heart beat. Arrythmia is caused by a defect in the generation or conduction of electrical impulses in the heart.

Arrhythmia or dysrhythmia

An abnormal rhythm or irregularity of the heartbeat. The heartbeat may either be too fast (tachycardia) or too slow (bradicardia). Arrhythmias may cause symptoms such as palpitation or light-headedness, but many have more serious consequences, including sudden death.

The availability of precise diagnostic methods, like electrocardiogram (ECG) Hotter monitors, event monitors, stress IQ tests, echocardiogram, cardiac catheterization, electrophysiology study (EPS), and head-up tiff table tests have led to increase in the diagnosis rate of cardiac arrhythmias, thus contributing to increased prescription of therapeutics for cardiac arrhythmias.
The evolving role of ambulatory arrhythmia monitoring in general clinical practice.
The company said the RhythmAnalytics platform uses an enhanced deep-learning technique to detect over 15 types of cardiac arrhythmias along with beat-by-beat morphology computation which include ventricular arrhythmias, ventricular ectopic beats and all non-paced arrhythmias including Atrial Fibrillation (AFib).
Vital to Control Your Risk Factors If you are diagnosed with a heart arrhythmia it's important to follow through on lifestyle modifications that can protect your cardiovascular health.
Objective: To classify different types of arrhythmias and to study their frequency and presentations among young male soldiers up to 40 years of age who have structurally normal heart.
A person who is suffering from cardiac arrhythmia for a long time is at increasing risk of cardiac arrest as the electric system of the person is not functioning properly.
In this paper, we have proposed an efficient system, which can classify ECG records into normal and diseased classes, that is, differentiating between the existence and absence of arrhythmia. The dataset has been taken from University of California at Irvine (UCI) machine learning repository and multiclass classification is applied to classify the records into one of the 16 given classes.
The prevalence of sinus arrhythmia was found at higher prevalence rate 22.50 percent (9/40) followed by atrial fibrillation 20.00 percent (8/40), sinus tachycardia 10.00 percent (4/40) and left ventricular enlargements 10.00 percent (4/40).
In our study, 3.15% patients were having severe hypomagnesaemia and all of these patients have torsade de pointes as the presenting arrhythmia suggesting that severe hypomagnesaemia is an important cause of torsade de pointes.
The antiarrhythmic effect appeared to strengthen with more prolonged allopurinol treatment, reaching a 28% reduction in ventricular arrhythmia incidence among patients on allopurinol for more than 2 years, compared with patients who never received the uric acid reducer, Jasvinder A.
Examination revealed a sinus arrhythmia with isolated supraventricular premature complexes, supraventricular couplets, and periods of supraventricular trigeminy lasting up to fifteen seconds (Figure 1).
