... innovations in visualizing intracardiac signals. Today we are recognized worldwide as an industry leader in developing innovative solutions to cardiac arrhythmias. Guided by the needs of electrophysiologists and their patients, we have pioneered innovative technology advancements ranging from the first deflectable tip catheter to the LASSO Circular Mapping Catheter to todays most sophisticated ...

... "At one extreme a muscle may be fully relaxed when much electromyograph evidence shows no activity, the muscle is electrically silent. This contrasts with earlier accounts by electrophysiologists who held that full relaxation was still accompanied by background activity rotating among a few units. Misconceptions concerning such muscle tonus were based on these views. ...
