Can daily recurrent sinus tachycardia episodes of 150-170/pm eventually cause cardiomyopathy?

In brief: If persistent

Not if they're sporadic but only if persistent (meaning day and night for weeks on end).
Sinus tachycardia will slow at night when you sleep and won't lead to any heart damage. If your hr is persistently elevated at >150, it's likely not sinus tachycardia but another type of tachycardia and that can cause tachycardia mediated cardiomyopathy.
