No, they are not the same (I have given the definitions of both below; this should help you know what each is and what is the difference between the two).
Heart attack: Is caused when there is a blockage in the main arteries (coronary arteries) of the heart.
Cardiac Arrest: occurs when the heart suddenly stops beating.
Sorry, but Cardiac Arrest does not usually occur when the heart "suddenly" stops beating. Cardiac arrest is the worst manifestation of cardiac compromise from an acute coronary event. It happens for a number of reasons, for example if a person has had extensive bleeding and there's not enough blood within the body for the heart to pump, or when the pumping action of the heart becomes ineffective. Maybe the electrical impulses have been disrupted or the heart is not responding properly to the electrical impulses and is "twitching", most commonly known as ventricular fibrillation. That's where CPR and Automated External Defibrillation come in. If cardiac arrest occurred when the heart "suddenly stopped beating" CPR and AED's would be mostly ineffective. Time is of essence. CPR needs to be started w/in 10 minutes of the fibrillation attack/cardiac arrest, or chances are it will be too late for resuscitation. Severe brain and heart damage will have occurred by that point. Cardiac arrest victims are sometimes said to have suffered "sudden death" but that means that the patient died within one hour of the onset of the signs and symptoms. In "sudden death" autopsies typically show the patient did not really have an actual cardiac arrest but usually had significant artherosclerotic heart disease

How likely are you to have cardiac arrest at 26?
The chances are unlikely (but not impossible). The older you are, the higher the chances. PS. Cardiac arrest is not the same as heart attack (however, what I said above applies to both).
Does cardiac muscle and heart have the same relationship?
The heart is composed of cardiac muscle fibers. It is the same thing.
Is cardiac arrest is the same thing as a flat line on a EKG?
Basically. Sometimes people also refer to continually non-conducted beats (i.e. p waves are present) as cardiac arrest.
What is cardiac distress?
Cardiac distress is the same thing as a myocardial infarction, or heart attack.
The layer of the heart that is the same as the cardiac serous membrane is?
epicardium
What is a cardiopulmonary arrest?
Is There a Difference Between a Sudden Cardiac Arrest and a Heart Attack? * A heart attack and sudden cardiac arrest are not the same thing. * A heart attack is technically known as myocardial infarction, although a person suffering a heart attack certainly has an increased risk of a sudden cardiac arrest. * The term cardiac arrest is also used to describe the sudden loss of function of the heart, as result of an abrupt disturbance in the heart's rhythm. It can occur in a person with or without heart disease. The basic difference is summarized below: Who can be affected by Sudden Cardiac Arrest? * People often ask who can be affected by sudden cardiac arrest, anticipating it is the fate of the elderly. Although the frequency and risk of SCA certainly increases with age it can occur without warning or symptoms to anyone, even teenagers. * According to the Australian Resuscitation Council an estimated 30,000 people a year suffer sudden cardiac arrest. Although pre-existing heart disease is a common cause for cardiac arrest, many victims never previously exhibit heart problems. * The survival rate for SCA without immediate treatment is low in the vicinity of 5 to 10 %, whereas survival rates well above 50% have been achieved following successful implementation of CPR and defibrillation, the shorter the time span of treatment the higher the survival rate. Is it possible to reverse the effect of sudden cardiac arrest? Yes, it is entirely possible to reverse the effect of a sudden cardiac arrest, particularly if the unconscious victim receives immediate aid by restoring the circulation with cardiopulmonary resuscitation (CPR) and delivery of defibrillation to restore the normal heart rhythm. If these life saving measures are delayed the prospect of a complete recovery diminishes. HEART ATTACK Cause: An occlusion or blockage in an artery that supplies blood to the heart - typically the coronary artery. Once the artery is blocked the heart muscle dies as a result of oxygen deprivation, resulting in a heart attack Warning Signs: Chest and arm pain, upper abdomen and jaw pain also common, sweating, weakness, dizziness, nausea, vomiting are all common symptoms Patient Response: Usually remains conscious and alert, usually distressed and anxious. Survival Prospects: Generally good, with appropriate treatment SUDDEN CARDIAC ARREST Cause: An abnormal or irregular heart rhythm (cardiac arrhythmias) occurs. Instead of the heart beating in a coordinated fashion, the ventricles (lower chambers) quiver or wobble - a process known as ventricular fibrillation, resulting in a cardiac arrest Warning Signs: Sudden collapse, usually no detectable pulse Patient Response: Unconscious and totally unresponsive, usually no pulse, and not breathing Survival Prospects:Generally poor 90+% will die unless CPR and defibrillation is administered within 10 minutes of collapse. Some people simply don't respond to treatment because of underlying medical conditions Page 12, Sensitive Hearts Newsletter Newsletter, Summer 2005-06 Sensitive Hearts is a publication of the Australian Sudden Arrhythmia Death Syndromes (SADS) Foundation.

What was the cause of Michael Jackson's death?
On June 25th 2009 police received a call at 12:30pm from Michael Jackson's Bel-Air mansion. Paramedics rushed to the scene and found Michael Jackson in a coma, not breathing. He was rushed to UCLA Medical Center in Los Angeles, CA. "The King of Pop" died the same day, June 25th 2009 2:26pm, due to cardiac arrest (heart stoppage), at the age of 50. Cardiac arrest is different from a heart attack, when you have a heart attack, your heart still beats, at least initially, sending blood/oxygen around the body. Blood flow to the heart itself is blocked, and this can damage the heart. A severe heart attack can cause a cardiac arrest. When you go into cardiac arrest, your heart stops completely. Most adults who are not resuscitated after around ten minutes will die due to lack of oxygen flow to the brain. On August 28th 2009 the cause of Jackson's cardiac arrest was reported as a combination of the potent drugs propofol, lorazepam and midazolam. The death was classified as a homicide, and law enforcement officials were investigating the actions of his personal physician, Dr. Conrad Murray.
What would happen to cardiac output if the stroke volume increased and the heart rate stayed the same?
Since the stroke volume increased then the cardiac out put would increase, pumping out more blood with the same amount of heart beats.
What happens to the heart rate as the cardiac muscles get stronger?
Resting heart rate goes down (maximum stays the same).

Involuntary muscle tissue found in the heart?
Cardiac muscle tissue is the involuntary muscle tissue found in the heart. It is striated and contracts to pump blood throughout the body. This type of muscle is highly specialized and functions to maintain the continuous beating of the heart.
