I would encourage you to smoke INDICA based strains that will not promote the anxiety attacks and panic symptoms you have described. Tingly lips and numb hands are common anxiety symptoms during a panic attack. The majority of these seemingly real physical ailments are in fact all psychological.

Heart palpitations and even "irregular" heart rythyms are not at all uncommon, in fact they are very common but most people are not very much in tune with their own bodies to even notice or pay attention to them. The vast majority of palpitations are completely harmless and can be brought on by stress related chemicals in your body such as adrenaline being released in a "fight or flight" scenario or during periods of prolonged stress.

Diet also plays a big role in this and you could be dehydrated, have low calcium or magnesium levels, & even potassium can cause heart related issues. Drink lots of water, take a quality cal/mag/zinc supplement and eat bananas on a regular basis.

Stay away from the paranoid heart racing tropical sativas and "regs" as we call them. Strains like Sweet Tooth, Blueberry, Northern Lights, Kush, Afghani, anything that is primarily INDICA is a much better bet for smokers with anxiety. Your expectations and fears also play a huge part in how weed affects you when you smoke though. Just let go and enjoy the experience, don't overdo it & remember, you will not die. You will not stay stoned forever, and whatever you are feeling will pass because you are in control.
