There are many ways to classify human arrhythmias, each of them having its particular interest in terms of theoretical comprehension, clinical management or. An alternative is to use computational techniques for automatic classification. A full automatic system for arrhythmia classification from signals acquired by a ECG. In view of the broad spectrum of arrhythmias and their considerable spontaneous variability, there is a need for a classification of arrhythmias as a basis for.

Classification of arrhythmias.

In the Figure we indicate with thick blue the atrioventricular node and the His bundle. Sinus bradycardia Healthy and elderly people sometimes present cardiac frequencies below 50 bpm.

Healthy trained athletes and young adults at rest or at night can classification of arrhythmias low heart rates even of less than 30 bpm without symptoms or an increased cardiovascular risk.

Various diseases myocardial infarction, hypothyroidism, intracranial hypertension and certain drugs amiodarone, morphine, beta-blockers, verapamil, diltiazem, digoxin can produce sinus bradycardia.

Classification of arrhythmias also appears when there is a predominance of vagal tone vasovagal syncope, vomiting, abdominal surgery. Sometimes sinus bradycardia is due to the aging or to a disease leading to a degeneration of the sino-atrial node.

Sinus b radycardia rarely produce symptoms if the frequency is no lower than 50 bpm.

When the frequency is lower than 50 bpm symptoms can appear because the heart does not pump enough blood towards the various tissues of the body. This may cause dizziness, weakness, instability, fatigue, tiredness, low classification of arrhythmias pressure, fainting feeling of impending fainting or syncope fainting or loss of consciousness.

Overview of cardiac arrhythmias

Bradycardia or asymptomatic intracardiac blocks do not require treatment. If the bradycardia is symptomatic, treatment should be aimed at controlling the triggering causes. If a drug is the cause, the suppression of treatment may be sufficient. When bradycardia or classification of arrhythmias blocks produce symptoms e.

In this case the heart is not activated, either because pulses are not generated in the sino- atrial node or because the pulses generated at this level are blocked at some point in the atrium.

The pauses usually last for several seconds and can cause recurrent syncope. An implantable pacemaker is recommended in patients with pauses of 3 or more seconds. Sick classification of arrhythmias syndrome sinus node dysfunction.

This is a cardiac arrhythmia presumably caused by a malfunction of the sino-atrial node, the heart's pacemaker. This arrhythmia is related to disorders that cause scarring, degeneration, or damage of the cells forming the sinus -atrial node due to cardiac diseases leading to fibrosis, classification of arrhythmias o amiloidosis.

Thus, it is more frequent in elderly people and often is intermittent.

Patients present bradycardia which dizziness, palpitations, fatigue, chest pain, unsteadiness, loss of concentration, irritability or fainting syncope due to cardiac arrest asystole. In these patients is necessary to implant an artificial cardiac pacemaker. Bradycardia-tachycardia syndrome, is classification of arrhythmias variant of sick sinus syndrome in which slow and fast heart artes alternate.

Back to top Atrio-ventricular AV conduction block In this case, the pulses that have invaded the atrium are conducted with delay or they are not conducted through the atrio-ventricular node to the ventricles. The blockade of impulse classification of arrhythmias may occur in the AV node or in the His bundle and in its branches.

AV block can occur in trained young athletes during sleep. It can also be p roduced by some drugs digoxin, beta -blockers, verapamil, diltiazem, amiodaroneinfections viral infections, rheumatic fever or classification of arrhythmias heart diseases e.
