In patients with acute ST-segment elevation myocardial infarction, the recommended dose of Lovenox is a single IV bolus of 30 mg plus a 1 mg/kg SC dose followed by 1 mg/kg administered SC every 12 hours (maximum 100 mg for the first two doses only, followed by 1 mg/kg dosing for the remaining doses).
Hardware failures inside the engine can also cause rough idle problems and misfires. Anything higher than the crankshaft itself is a likely culprit, but that doesn't mean the bearings or crankshaft itself aren't.
If the carbureted vehicle continues to idle too high after warming up, it may have a defective power circuit or accelerator pump. Replacing the accelerator pump or carburetor usually brings the idle speed to normal. Ignition problems sometimes lead to a fast idle.
