Marijuana Induced Sick Sinus Syndrome: A Case Report.

Area of Science:

• Cardiology
• Toxicology

Background:

• Marijuana is a frequently abused illicit substance in the US.
• Regular marijuana use is associated with adverse cardiovascular effects.
• This case explores the link between marijuana abuse and sick sinus syndrome.

Observation:

• A 27-year-old male presented with recurrent syncope over 5 years.
• He denied alcohol/nicotine use but reported daily marijuana use.
• Investigations ruled out other causes, but a loop recorder confirmed prolonged sinus pauses, indicating sick sinus syndrome.

Findings:

• The patient's drug screen was positive for marijuana.
• Sick sinus syndrome was diagnosed in the context of chronic marijuana abuse.
• The patient's condition improved after pacemaker implantation.

Implications:

• Marijuana abuse may be a reversible cause of sick sinus syndrome.
• This case suggests a potential link between marijuana use and cardiac arrhythmias.
• Further research is needed to understand the relationship between marijuana and sick sinus syndrome.
