Conclusion
CVS patients presenting with ventricular arrhythmias frequently continue
to be treated medically with no device therapy. Our observation stresses
on two issues. First, coronary spasm can be responsible for SCD. Second,
a specific “shark fin” pattern on ECG may predict an arrhythmogenic
propensity. Prompt recognition of this pattern while managing CVS
patients and CVS-related ventricular arrhythmias should lower the ICD
implantation threshold.
