Patients with congestive heart failure (CHF) having a compromised blood supply, are at greater risk of sudden cardiac death (SCD). With an estimated incidence as high as 22% among these patients, current clinical guidelines recommend using implantable cardioverter defibrillators (ICDs) to help mitigate the risk of SCD.

Patients with such variants can present with a wide spectrum of arrhythmias but sudden death is generally considered rare. Pathogenic genetic variants in the HCN4 (hyperpolarisation-activated and cyclic nucleotide-gated channel) gene can cause sinus node dysfunction, disrupting the function of the pacemaker region of the heart.
