Is heart rate a part of the autonomic system? Do antipsychotics raise heart rate? Do antipsychotics damage autonomic system thereby raising heart rate
Yes, sometimes, no: That about sums it up.Get a more detailed answer ›
RHYTHYM Support: Pacing and pacemakers have been with us decades now. For individuals with low pulse/ heart block a fib etc symptoms of syncope or death can occur. Electrical wires can be placed onto skin surface or surgically to the heart surfaces. These are tested for best thresholds, and attached to selected pacemaker/aicd or device with battery to send stimulus to the heart. ...Read moreSee 1 more doctor answer
All of them: Any tissue can do this, technically. The order of impulse formation is generally: sa node > atrium > proximal his tissues > av node > ventricles > purkinje fibers. But it can vary from person to person. ...Read more
The valsalva does: not slow the heart rate. It increases the heart rate during the time of increase in intrathoracic pressure due to restricted venous return. Wikipedia has a nice and easy to understand description: https://en.wikipedia.org/wiki/Valsalva_maneuver. If you mean slowing or breaking an episode of SVT it is from compensatory increased vagal tone. ...Read more
Shocks in arms: Lots of things could cause this, however the most common thing is neck pathology where the nerves travel down from the brain to to arms. If there is any narrowing or pinching of the nerves this could cause it. Be careful with your neck, it holds your head on. See your doctor for other causes that could present this way. ...Read moreSee 1 more doctor answer
Low qrs voltage in limb leads [qrs deflection 0.5 mv in limb leads] atypical ecg.... Healthy 27 years old what does this mean?
Low voltage: Low voltage on an electrocardiogram (ECG) can be a sign of cardiomyopathy (weak heart muscle), pericardial effusion (fluid around the heart), obesity, lung disease. thyroid disease, and others. In most cases you would already know that you have these conditions. It is possible that technical issues with the ECG recording created an error. I would repeat the tracing. Glad to look at it for you. ...Read more
Reset conduction: You heart has an electrical conduction system that controls how the heart muscle contracts. Often in cardiac arrest that conduction system is sending disordered electrical signals. The shock sometimes given during cpr/acls is an attempt to "reset" the conduction system so the electric signals go back to the proper order. ...Read moreSee 1 more doctor answer
Is this correct? "Wolff Parkinson white synd. is an electrical abnormality in the heart where an accessory pathway exists leading to rapid heart rate"
SVT Is the lifetime chance of devoloping venticular fibrillation due to accesory pathway capable of anterograde conduction <1% When ecg was normal?
Wpw : Extremely low if antegrade conduction so rare ...Read more
