symptoms typically include muscle pain, weakness, and being unable to release muscles after a contraction — for example, difficulty loosening their grip after grabbing onto something. slurred speech and locking of the jaw may also occur.
type ii is considered
less severe than type i and doesn’t necessarily result in a shortened lifespan. however, in some cases it can still affect mobility as well as major organs — such as the heart.
recurrent ventricular tachycardia
gottfried died of ventricular tachycardia (v-tach), an abnormal heart rhythm (arrhythmia) that causes the lower chambers of the heart to beat rapidly, according to
johns hopkins medicine.
in a healthy heart beat, or sinus rhythm, the four chambers of the heart have to beat in a regular, synchronized manner in order to pump the blood through the lungs and then out to the rest of the body. when certain chambers of the heart begin to bear erratically or out of sync, it can severely limit the blood that is sent to critical areas of the body like the brain and heart.
in v-tach, the two lower chambers of the heart beat so rapidly that they may not fill with enough blood to pump to the rest of the body, which can have devastating effects. in some instances the heart may correct itself within a few seconds, but longer episodes
can be fatal. symptoms of v-tach include chest pain, dizziness, heart palpitations, light-headedness and shortness of breath.
