There are a number of differences between defibrillation and cardioversion. They are used to treat different types of issues, making it crucial that you know which technique to employ when a patient has an emergency in your vicinity. Using the wrong technique could have some extremely dire effects on the chest of the patient, and can even cause the heart to go into cardiac arrest.
A defibrillation is a form of treatment that is used for patients who are facing immediately life-threatening arrhythmias where the patient in question does not have a pulse. Forms of defibrillation include both ventricular fibrillation and pulseless ventricular tachycardia.
On the other hand, cardioversion relates to any procedure with the aim of converting an arrhythmia back to sinus rhythm. When a patient has an unstable heart rhythm or has already tried chemical cardioversion, then electrical cardioversion is used in order to ensure their safety. Scenarios in which cardioversion is used are generally associated with pulmonary edema, hypotension, chest pain, or syncope. The technique is used less frequently in situations such as atrial fibrillation in order to revert the heart rhythm back to a sinus rhythm.
Both of these treatment processes aim to deliver electrical energy to the heart in order to stun it momentarily. This allows for a normal sinus rhythm to kick in due to the heart’s regular pacemaker known as the sinoatrial node
Differences Between Monophasic and Biphasic Systems
The current in monophasic systems only flows in one direction, from one paddle to the next.
The current in biphasic systems moves towards the positive paddle, then reverses and returns several times.
Biphasic shocks are associated with fewer burns and less myocardial damage since they produce one cycle every 10 milliseconds.
The rate of first shock performance in cardiac arrests due to a shockable rhythm is only 60% with monophasic shocks, but it rises to 90% with biphasic shocks.
However, biphasic defibrillators’ effectiveness over monophasic defibrillators has not been reliably reported.
Types of Defibrillators
Automated External Defibrillators (AEDs) are the most commonly known types of defibrillators. They are often the first choice of an organization due to them being extremely useful, as well as the fact that they do not require any special medical training to properly utilize. These types of defibrillators are often found in public venues such as offices, shopping centers, airports, and other similar public buildings. The work by analyzing the heart rhythm of the patient, and then charging and delivering an appropriate shock to their heart in order to correct the rhythm. Unfortunately, these devices cannot be overwritten, and in some cases, can take between 10 and 20 seconds to identify arrhythmias. However, the ease of use, as well as the speed of these devices, makes them a popular choice for many.
Risks Associated with Defibrillation
It’s extremely unlikely for a well-maintained, stable defibrillator to malfunction. The unit assesses and measures the victim’s heart rhythm. The device then provides you with a number of instructions that you should follow in order to save the life of the individual in trouble. By following the instructions provided to you, you ensure that you are not doing anything wrong, even if you have no prior medical training.
It’s more likely that you’ll sustain an injury while practicing CPR, as broken ribs are common, particularly among the elderly. You risk aggravating their injuries by pushing them into the protected airway location. These potential problems are the lesser of two evils as compared to what can happen if you don’t obey the chain of survival for treating a sudden cardiac arrest.
