Although this condition only affects the voluntary muscles, several children have had cardiac arrest, possibly due to the additional stress placed on the heart. [2] X-linked myotubular myopathy was traditionally a fatal condition of infancy, with life expectancy of usually less than two years. There appears to be substantial variability in the ...
The condition presents early in life and the average life expectancy is 2.5 years with death most commonly caused by ventricular arrhythmias. Many children with Timothy syndrome who survive longer than this have features of autism spectrum disorder. Timothy syndrome is caused by variants in the calcium channel Cav1.2 encoded by the gene CACNA1c.
Cardiomyopathy is a group of primary diseases of the heart muscle. [1] Early on there may be few or no symptoms. [1] As the disease worsens, shortness of breath, feeling tired, and swelling of the legs may occur, due to the onset of heart failure. [1]
Cardiac arrest (also known as sudden cardiac arrest [SCA] [11]) is when the heart suddenly and unexpectedly stops beating. [ 12 ] [ 1 ] When the heart stops beating, blood cannot properly circulate around the body and the blood flow to the brain and other organs is decreased.
It is an uncommon cause of unexplained heart failure in infants and children, and is one component of HEC syndrome. Fibroelastosis is strongly seen as a primary cause of restrictive cardiomyopathy in children, along with cardiac amyloidosis , which is more commonly seen in progressive multiple myeloma patients and the elderly.
While playing baseball in Lake Worth, Florida, 6-year-old Oscar Stuebe was hit by a fly ball that sent him into cardiac arrest. Due to quick thinking and CPR from his mother, Sarah Stuebe, Oscar ...
According to the American Heart Association, out-of-hospital cardiac arrest can affect more than 300,000 people in the United States each year. [5] Three minutes after the onset of cardiac arrest, a lack of blood flow starts to damage the brain, and 10 minutes after, the chances of survival are low. [6]
With the advent of these strategies, cardiac arrest came to be called clinical death rather than simply death, to reflect the possibility of post-arrest resuscitation. At the onset of clinical death, consciousness is lost within several seconds, and in dogs, measurable brain activity has been measured to stop within 20 to 40 seconds. [2]
