TCAs usually cause sinus tachycardia, which does not seem to be a problem for most people.
If someone had underlying heart disease, I would be concerned about sinus tachycardia. I would also be concerned in the elderly, who often have latent coronary artery disease. In young people with no medical problems, I would not be particularly worried (unless the tachycardia was either severe or symptomatic).
The cardiac toxicity of TCAs in overdose is a completely different issue. This is mainly due to their activity at ion channels in the cardiac conduction system. The tachycardia, on the other hand, it mainly caused by.....
1. The anti-cholinergic effect
2. The NE reuptake inhibition
3. Occasionally, a reflex increase due to hypotension
