One reason patients ignore the symptoms of ventricular tachycardia is that they are similar to ones you might feel after skipping a meal or two. If you’re fasting, people complain of dizziness, lightheadedness and feeling like you’re about to pass out. In some cases, you may even pass out as a result of this condition. You might also have heart palpitations or chest pain. There may be associated nausea and shortness of breath. The worst symptom of possible ventricular tachycardia is cardiac arrest and death.
