1. A medical device comprising:
a sensing circuit including an over-range condition, the sensing circuit configured to:
sense an electrical signal produced by a patient's heart;
determine that the sensed electrical signal meets the over-range condition:
detect from the sensed electrical signal a first type of pulse in response to at least determining that the sensed electrical signal meets the over-range condition;
modify the sensed electrical signal in response to detecting the first type of pulse by removing the first type of pulse from the sensed cardiac electrical signal;
a control circuit configured to detect a tachyarrhythmia by processing the modified sensed electrical signal; and
a therapy circuit configured to deliver a tachyarrhythmia therapy in response to the control circuit detecting the tachyarrhythmia.
