SUDDEN CARDIAC ARREST AWARENESS MONTH!

 

 

Cardiac arrest is the abrupt loss of heart function in a person who may or may not have diagnosed heart disease. The time and mode of death are unexpected. It occurs instantly or shortly after symptoms appear.

Each year, more than 420,000 emergency medical services-assessed out-of-hospital cardiac arrests occur in the United States.

No. The term “heart attack” is often mistakenly used to describe cardiac arrest. While a heart attack may cause cardiac arrest and sudden death, the terms don’t mean the same thing. Heart attacks are caused by a blockage that stops blood flow to the heart. A heart attack (or myocardial infarction) refers to death of heart muscle tissue due to the loss of blood supply, not necessarily resulting in the death of the heart attack victim.

Cardiac arrest is caused when the heart’s electrical system malfunctions. In cardiac arrest death results when the heart suddenly stops working properly. This may be caused by abnormal, or irregular, heart rhythms (called arrhythmias). A common arrhythmia in cardiac arrest is ventricular fibrillation (VFib). This is when the heart’s lower chambers suddenly start beating chaotically and don’t pump blood anywhere. Death occurs within minutes after the heart stops. Cardiac arrest may be reversed if CPR (cardiopulmonary resuscitation) is performed and a defibrillator is used to shock the heart and restore a normal heart rhythm within a few minutes.

Heart Attack vs Cardiac Arrest:

People often use these terms interchangeably, but they are not synonyms. A heart attack is when blood flow to the heart is blocked, and sudden cardiac arrest is when the heart malfunctions and suddenly stops beating unexpectedly. A heart attack is a “circulation” problem and sudden cardiac arrest is an “electrical” problem.

What is a heart attack? A heart attack occurs when a blocked artery prevents oxygen-rich blood from reaching a section of the heart. If the blocked artery is not reopened quickly, the part of the heart normally nourished by that artery begins to die. The longer a person goes without treatment, the greater the damage. Symptoms of a heart attack may be immediate and intense. More often, though, symptoms start slowly and persist for hours, days or weeks before a heart attack. Unlike with sudden cardiac arrest, the heart usually does not stop beating during a heart attack. The heart attack symptoms in women can be different than men.  A heart attack actually caused scarring to the heart since it causes damaging to the heart muscle tissue.

What is cardiac arrest? Sudden cardiac arrest occurs suddenly and often without warning. It is triggered by an electrical malfunction in the heart that causes an irregular heartbeat (arrhythmia). With its pumping action disrupted, the heart cannot pump blood to the brain, lungs and other organs. Seconds later, a person loses consciousness and has no pulse. Death occurs within minutes if the victim does not receive treatment.

Arrhythmia’s can be:

Premature Ventricular Contractions (PVCs) are below in a normal sinus rhythm (best rhythm to be in) below and if PVCs get more frequent making the rhythm more irregular it can go into a further dysrhythmias , like Ventricular Tachycardia even Ventricular Fibrillation, which could lead into a heart attack or cardiac arrest especially if Ventricular Tachycardia left untreated and especially Ventricular Fibrillation (see rhythms below).

Below PVC’s are in normal sinus rhythm (the best rhythm you could be in)

What to do: Heart Attack Even if you’re not sure it’s a heart attack, don’t wait more than five minutes to call 9-1-1 or your emergency response number. Every minute matters! It’s best to call EMS to get to the emergency room right away. Emergency medical services staff can begin treatment when they arrive — up to an hour sooner than if someone gets to the hospital by car. EMS staff are also trained to revive someone whose heart has stopped. Patients with chest pain who arrive by ambulance usually receive faster treatment at the hospital, too.

What to do: Sudden Cardiac Arrest Cardiac arrest is reversible in most victims if it’s treated within a few minutes. First, call 9-1-1 for emergency medical services. Then get an automated external defibrillator if one is available and use it as soon as it arrives. Begin CPR immediately and continue until professional emergency medical services arrive. If two people are available to help, one should begin CPR immediately while the other calls 9-1-1 and finds an AED.  Learn CPR  you may just save someone one day being at the right place at the right time.

Sudden cardiac arrest is a leading cause of death unfortunately – nearly 400,000 out-of-hospital cardiac arrests occur annually in the United States. By performing Hands-Only CPR to the beat of the classic disco song “Stayin’ Alive,” you can double or even triple a victim’s chance of survival.

Recognize sudden cardiac arrest (SCA). If a person is unresponsive and not breathing normally, assume it is SCA.

1 Call 911 and follow dispatcher instructions.

2 Start CPR. Push hard and fast on the center of the chest at a rate of 100-120 beats per minute (e.g., to the tune of “Baby Shark” or “Staying Alive”).

3 Use the nearest AED as quickly as possible to restart the heart.
