Congestive heart failure, and Bradycardia

Atrial standstill is a rare cardiac rhythm disease with a few familial and sporadic cases described to date that is characterized by a transient or permanent absence of electrical and mechanical atrial activity. Electrocardiographic findings include bradycardia, ectopic supraventricular rhythms, lack of atrial excitability and absent P waves.

Atrial standstill (AS) is a rare condition characterized by the absence of electrical and mechanical activity in the atria. On surface ECG, AS is distinguished by bradycardia, junctional (usually narrow complex) escape rhythm, and absence of the P wave. Nearly 50% of patients with AS experience syncope. AS can be persistent or transient, and diffuse or partial (summary by Fazelifar et al., 2005).

Combined oxidative phosphorylation deficiency-28 (COXPD28) is a complex autosomal recessive multisystem disorder associated with mitochondrial dysfunction. The phenotype is variable, but includes episodic metabolic decompensation beginning in infancy that can result in mild muscle weakness, cardiorespiratory insufficiency, developmental delay, or even death. Biochemical studies of patient tissues show variable mitochondrial defects, including decreased activities of respiratory chain enzymes (summary by Kishita et al., 2015).For a discussion of genetic heterogeneity of combined oxidative phosphorylation deficiency, see COXPD1 (OMIM ).

Familial dilated cardiomyopathy with conduction defect due to LMNA mutation is a rare familial dilated cardiomyopathy characterized by left ventricular enlargement and/or reduced systolic function preceded or accompanied by significant conduction system disease and/or arrhythmias including bradyarrhythmias, supraventricular or ventricular arrhythmias. Disease onset is usually in early to mid-adulthood. Sudden cardiac death may occur and may be the presenting symptom. In some cases, it is associated with skeletal myopathy and elevated serum creatine kinase.

Mitochondrial hypertrophic cardiomyopathy with lactic acidosis due to MTO1 deficiency is a rare mitochondrial oxidative phosphorylation disorder with complex I and IV deficiency characterized by lactic acidosis, hypotonia, hypertrophic cardiomyopathy and global developmental delay. Other clinical features include feeding difficulties, failure to thrive, seizures, optic atrophy and ataxia.
