Types of Arrhythmia and Tampa CPR Classes for Cardiac Emergencies

Most sudden cardiac deaths (SCD) are caused by abnormal heart rhythms called arrhythmias with the most common life-threatening arrhythmia being ventricular fibrillation, which is an erratic firing of impulses from the ventricles. It reduces the heart’s ability to pump blood and death will occur within minutes, if left untreated. Emergency treatment includes cardiopulmonary resuscitation (CPR) and defibrillation where the former keeps enough oxygen in the lungs and gets it to the brain until the normal heart rhythm is restored with an electric shock to the chest (defibrillation).

For a CPR certification Tampa, make sure to select a certified training site such as the AHA accredited CPR Tampa in Florida. Certified and experienced instructors conduct the classes that involves both theoretical and practical training. Become AHA certified at the end of the training classes after successfully passing a skills test and written exam.


Arrhythmia Types:
Arrhythmia is common for all to be classified in two principal ways:
Where in the heart the arrhythmia originates – in the upper chambers or the lower chambers
1.      Lower chamber origin: ventricular arrhythmia
2.      Upper chamber origin: supraventricular origin
Whether the arrhythmia increases or decreases the ticker rate
1.      Tachycardia: Too Fast
2.      Bradycardia: Too Slow

Ventricular- Arrhythmias occurring in the atria (the top chambers of the ticker) are supraventricular (above the ventricles) in origin, whereas ventricular arrhythmias start in the ventricles (the lower chambers of the ticker). The heart’s main pumping chambers are the ventricles, and the majority of the potentially lethal arrhythmias are ventricular in origin.

Supraventricular- Like we have already mentioned that arrhythmias that occur in the atria (the top chambers of the heart) are supraventricular (above the ventricles) in origin which aren’t responsible for dramatic events such as sudden cardiac death, but the most common arrhythmia, atrial fibrillation, is supraventricular and can lead to fatal strokes.

Bradycardia- A healthy ticker normally beats in a steady and coordinated way which slows down or speeds up depending on the body’s needs. The rate at which your heart beats is important because it influences how much oxygenated blood circulates around the body.

The heart rhythm under normal control is referred to as sinus rhythm during which the ticker’s natural pacemaker controls the rhythm. This pacemaker gets affected by the hormones and nervous system of the body that helps in determining the heart rate. Bradycardia is a heartbeat that’s too slow and a heartbeat too fast is called tachycardia.

Arrhythmia Causes:
Pacemaker Problems and Conduction problems (where an electrical pulse’s path is blocked or where the electrical signal somehow circles back to stimulate a second pulse instead of naturally ending).

Symptoms:
Some arrhythmias have no symptoms; while others are dramatically debilitating with some relatively common arrhythmia symptoms being fainting, dizziness, premature beats, palpitations or skipped beats, lightheadedness and fatigue.

Direct and Less Direct Signs of Heart Problems and Tampa BLS Classes

Chest tightness, pressure and pain are the classic signs of heart trouble but they are far from its only signals which makes most people failing to connect other symptoms they are experiencing to their actual cause which often results in failing to get help during emergency heart issues like a heart attack or stroke, or a critical delay in getting possible cardiovascular disease diagnosed and treated. Cardiovascular disease not diagnosed or treated on time may lead to the occurrence of cardiac emergencies like a cardiac arrest or heart attack. These are life-threatening emergencies and a victim would require immediate treatment for survival. The most appropriate form of treatment is proper application of the life-saving CPR procedure which is a series of chest compressions and rescue breaths.
