torsade de pointes VT
torsade is an inherently unstable rhythm and will either revert or degenerate to VF, thus commence Rx as soon as it is recognised.
Most (75-82%) torsade de pointes (TDP) rhythms are started by a pause. Pacing at rates up to 140 bpm may prevent the ventricular pauses that allow TDP to originate.
often associated with prolonged QTc
on ECG which may be hereditary, drug-induced, or have other causes.
a rare cause is Brugada syndrome
which if untreated may be fatal within 2 years.
