Why the study?
Cardiac arrhythmias are frequent and potentially fatal complications of toxic substance consumption, including cannabis.
Cannabis overdose can induce focal atrial tachycardia that may resolve spontaneously without the need for pharmacological or electrical cardioversion.
May prompt arrhythmia evaluation after cannabis overdose; leaves open causal confirmation beyond single cases.
Cardiac arrhythmias are frequent complications of the consumption of toxic substances, including cannabis, which can be fatal. We report in this case a patient who developed a cardiac arrhythmia-type focal atrial tachycardia a few moments after the consumption of an important dose of cannabis but which reduced spontaneously and without having administered any medication or an external electric shock. All the rest of the etiological assessment of this arrhythmia was negative and the arrhythmia was linked to the consumption of cannabis which is known to cause these complications.
