Magnesium Cardiac Arrest
Frequent pvc's all day. Hr 62-74 pm, doctor recommended 400mg of magnesium before bedtime. Bit worried, read that to much mag can cause cardiac arrest?
Depends on: Why you had the cardiac arrest. If due to coronary artery disease, you should avoid simple carbs and get plenty of aerobic exercise. Look at lowglycemicindex. Com. Also avoid caffeine and stimulants. If another cause, like hocm, valve disease, arrhythmogenic right ventricular dysplasia or some other cause, look to treat the underlying cause first. ...Read more
Stopped heart: Cardiac arrest occurs when the heart stops pumping blood forward. The stoppage is usually due to to a change in the heart's electrical rhythm that prevents the muscle cells from squeezing in an organized fashion. Cardiac arrest can also occur with a normal heart rhythm, if the heart is too weak to pump blood or too empty to have blood to pump. In any case, immediate resuscitation is needed. ...Read more
Heart stops: Cardiac arrest is when the heart stops beating effectively. The heart actually ceases to beat or the heart has other electrical rhythm disturbances in which the heat no longer can work as a pump. Because of the lack of blood flow to the brain, patients become comatose, and stop breathing. Unless the condition is reversed quickly, death follows. CPR can provide some protection until help arrives. ...Read more
Heart disease: A cardiac arrest patient will rapidly lose consciousness, no pulse, no audible heart tones, no response to stimuli, the patient will also rapidly lose spontaneous respiration. ...Read more
Yes......: During a cardiac arrest, the heart stops contracting so that there is no blood being circulated to the organs. Cardiopulmonary resuscitation is performed to restore contractility. If successful, the person survives. The longer it takes to "re-start" the heart, the more likely there will be residual effects, like brain injury due to decreased oxygen to the brain during the arrest. ...Read more
CPR: Take a cprcourse so you know how to help in that situation. Learning CPR is not difficult and neither is using an automated defibrillator if available. ...Read more
Long list: Sudden cardiac death had several causes: Coronary disease or heart attack may cause sudden cardiac death, but also sudden death can occur in patients with cardiac abnormality of the heart muscle that can be detected on echo cardiogram and sometime undetected on cardiac echo, electrical genetic anomaly may cause sudden death ...Read more
Electrolytes: Bulimia lends itself to upsetting the normal chemistry in the blood which is needed to normal functioning of the heart. Not allowing the body to absorb nutrients prevents having the needed sodium and potassium levels. When this balance is off the heart may go into a toxic rhythm leading to death. ...Read more
Potentially: Hypoxia means an inadequate amount of oxygen in the blood. Is can lead to vital organs not receiving enough oxygen to survive. If the heart is starved for oxygen this can lead to ischemia or heart cell death which can cause either failure or an abnormal rhythm which leads to a cardiac arrest. ...Read more
Very rarely: Primary cardiac arrest (not related to choking, drowning, etc) is exceedingly rare in children but can happen. Structural problems in the heart that are present at birth can predispose to lethal rhythm problems. This is one of the arguments made to place aeds (automatic external defibrillators) in schools and gymnasiums. ...Read more
But usually for different etiologies (causes).
Most children and infants will have a cardiac arrest if they do not get enough air (oxygen) and this will cause the heart rate to decrease to a point where the heart can stop (systole) or go into an abnormal rhythm. Also cardiac defects or anatomic abnormalities from birth can do this too. The best treatment is CPR and call 911. ...Read more
